Product details
Overview
ISL34341INZ from Intersil is a bidirectional 24-bit LVCMOS video SERDES IC supporting 6–40MHz pixel clocks, DC-balanced 8b/10b encoding, internal 100Ω differential termination, and bi-directional side-channel data transport over a single 100Ω differential pair - used in long-reach automotive navigation displays and remote camera links.
For engineers reviewing the ISL34341INZ datasheet, ISL34341INZ pinout, ISL34341INZ application, or ISL34341INZ equivalent, key selection considerations include serializer/deserializer role configuration via VIDEO_TX pin, I2C master capability across the link, programmable transmitter boost/pre-emphasis (16 settings), receiver equalization, and hot-plug resynchronization every video line.
Technical Context
The ISL34341INZ implements a 30× PCLK_IN serial multiplier for 24-bit RGB + sync signals, with embedded 8b/10b line coding enabling AC-coupling and ground-shift immunity. Its CDR recovers clock from the serial stream using REF_CLK fed into PCLK_IN, requiring <5000ppm frequency offset tolerance and stable amplitude.
Side-channel operation occurs during vertical blanking intervals, supporting up to 224 bytes per VSYNC period in each direction without consuming video bandwidth. I2C master mode allows local controller access to remote slave devices via the same differential link, with address pins I2CA[3:0] setting one of 16 device addresses (e.g., 0x60 when all low).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pixel Clock Range | 6–40MHz - supports WSVGA 1024×600 @ 60fps (8% blanking) and SVGA 800×600 @ 70fps (16% blanking) |
| Video Interface | 24-bit RGB (RGBA/B/C[7:0]) + HSYNC/VSYNC/DATAEN - bidirectional LVCMOS parallel I/O depending on VIDEO_TX state |
| Serial Interface | Single 100Ω differential pair (SERIOP/SERION) with internal termination - no external resistors required |
| Encoding | 8b/10b - ensures DC balance for AC-coupling and reduces EMI; enables reliable long-cable transmission |
| Side-Channel Capacity | Up to 224 bytes per VSYNC period - transports auxiliary data (config, telemetry, I2C commands) during vertical blanking |
| Power Supply | 1.8V (VDD_CDR/VDD_CR) and 3.3V (VDD_IO/VDD_TX/VDD_P/VDD_AN) - strict sequencing required (3.3V before 1.8V) |
| I2C Support | Standard/fast-mode (100–400kHz); 4-bit address (I2CA[3:0]) with fixed 011 prefix - enables up to 16 devices on one bus |
Pinout & Package
ISL34341INZ is housed in a 64-lead Exposed Pad Thin Plastic Quad Flatpack (EPTQFP), JEDEC MS-026ACD-HU Issue D, package Q64.10x10C (10mm × 10mm body, 12.0mm × 12.0mm max outline, 1.0mm height, exposed thermal pad). Pin 1 identifier is marked by ejector pin mark (not pin #1 ID); lead pitch is 0.5mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIDEO_TX | Mode control input | High = serializer; Low = deserializer - enables single-device inventory and dual-role flexibility |
| SERIOP / SERION | Differential serial I/O | Full-duplex high-speed interface with internal 100Ω termination - eliminates need for external bias or termination components |
| RSTB/PDB | Reset & power-down control | Pulled high for normal operation; driven low for reset or sustained low for power-down (≤1mA total supply current) |
| RGBA/B/C[7:0] | Parallel video data | 24-bit RGB inputs (serializer) or outputs (deserializer) - LVCMOS-compatible, 3.3V tolerant |
| PCLK_IN / PCLK_OUT | Reference clock input / recovered clock output | PCLK_IN serves as PLL reference in deserializer mode; PCLK_OUT is jitter-controlled recovered clock (±20% spread when randomizer enabled) |
| I2CA[3:0], SCL, SDA, MASTER | I2C addressing & interface | Configurable 4-bit slave address; MASTER pin selects I2C master mode for remote slave access across the link |
| STATUS | Receiver status indicator | Open-drain CMOS output: High = valid 8b/10b lock; Low = loss of synchronization or invalid data |
| REF_RES | Analog bias reference | Connects to 3.16kΩ ±1% resistor to GND - sets internal bias currents for CDR and analog blocks |
Key Features
| Feature | Design Value |
|---|---|
| Single-device serializer/deserializer | Role selected by VIDEO_TX pin - reduces BOM count and simplifies logistics for display/camera pairs |
| Bi-directional side-channel | Transfers up to 224 bytes per VSYNC in both directions during blanking - enables remote register config and telemetry without extra wires |
| I2C master extension | Local controller accesses remote I2C slaves (e.g., touch controllers, sensors) through SERDES link - no additional I2C routing needed |
| Programmable signal conditioning | 16-step transmitter amplitude boost/pre-emphasis and receiver equalization - optimizes eye opening for varying cable lengths (up to 10m) |
| Hot-plug resynchronization | Automatic line-by-line relock after cable insertion/removal - maintains video continuity without system reset |
| Integrated 100Ω termination | On-chip differential termination on SERIOP/SERION - eliminates external resistors and improves layout reproducibility |
Applications
| Automotive Navigation Display | Industrial Remote Camera |
|---|---|
Use Scenario: Transmitting WSVGA video from head-unit processor to LCD display located in dashboard or center console over 5–8m cable.

Equivalent & Alternatives
The following parts are listed as comparable options for similar video SERDES applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9205+MAX9206 | Dual-chip solution (separate serializer/deserializer); no integrated side-channel; requires external I2C multiplexer for remote slave access | Lacks native bi-directional auxiliary transport - side-band data needs separate UART or SPI bridge | Choose when legacy MAXIM ecosystem integration is required and side-channel functionality is handled externally. |
| TI DS90UB925Q-Q1 | Automotive-qualified (AEC-Q100 Grade 2); includes built-in FPD-Link III compatibility; higher max PCLK (65MHz); no 8b/10b - uses scrambling instead | Designed for automotive infotainment with ASIL-B support; lacks native I2C master extension across link | Prefer for new automotive designs requiring functional safety compliance and higher resolution scalability beyond WSVGA. |
Compared with MAX9205+MAX9206 and DS90UB925Q-Q1, the ISL34341INZ uniquely combines single-device dual-role operation, integrated 8b/10b encoding for AC-coupling, and true bi-directional side-channel with I2C master extension - making it optimal for cost-sensitive, space-constrained industrial and avionics video links where full protocol transparency and minimal component count are critical.

FAQ
What is the operating temperature range for the ISL34341INZ?
The ISL34341INZ is rated for operation from –40°C to +85°C, matching its industrial-grade qualification and suitability for automotive navigation, avionics, and ruggedized industrial terminals. This range is explicitly defined in the ordering information and confirmed in the Absolute Maximum Ratings table of the FN6827 datasheet.
How does the ISL34341INZ handle clock recovery and jitter performance?
The ISL34341INZ uses a CDR circuit locked to the incoming serial stream, with PCLK_OUT exhibiting ≤0.5% rms period jitter (clock randomizer off) and ±20% spread width (randomizer on). REF_CLK must be applied only after full power-up (≥10ms delay post-1.8V) and maintained within ±5000ppm frequency accuracy to ensure stable lock - critical for ISL34341INZ video timing integrity.
Can the ISL34341INZ be used in both serializer and deserializer roles in the same design?
Yes - the ISL34341INZ is a single-device bidirectional SERDES. Its role is determined solely by the logic level on the VIDEO_TX pin: high = serializer, low = deserializer. This allows identical ISL34341INZ units to be deployed at both ends of the link, simplifying inventory and board design - a core feature confirmed in the datasheet overview and pin description tables.
What is the maximum cable length supported by the ISL34341INZ?
The ISL34341INZ supports up to 10m of 100Ω differential cable, enabled by 16 programmable settings for transmitter pre-emphasis and receiver equalization. Performance depends on cable quality and PCLK frequency; at 40MHz, robust operation is verified with 27nF AC-coupling capacitors and proper PCB layout per Figure 4 in the FN6827 datasheet - not a fixed value but a design-achievable limit for ISL34341INZ.
Does the ISL34341INZ require external termination resistors on the SERIOP/SERION lines?
No - the ISL34341INZ integrates 100Ω differential termination on the SERIOP and SERION pins, eliminating the need for external resistors. This is explicitly stated in the Features list ("Internal 100Ω termination on high-speed serial lines") and validated in the Pin Descriptions section, ensuring consistent impedance matching and simplified layout for ISL34341INZ implementations.
