Product details
Overview
ISL34340INZ-T13 from Intersil is a bidirectional 24-bit LVCMOS video SERDES IC supporting WSVGA 1024×600 @ 60fps over a single 100Ω differential pair, with integrated 8b/10b encoding, internal 100Ω termination, and I²C configuration. It operates from -40°C to +85°C in a 64-lead EPTQFP package and transports auxiliary data during vertical blanking for remote camera/display systems.
For engineers reviewing the ISL34340INZ-T13 datasheet, ISL34340INZ-T13 pinout, ISL34340INZ-T13 application, or ISL34340INZ-T13 equivalent, key selection criteria include PCLK_IN support up to 40MHz, serializer/deserializer role switching via VIDEO_TX pin, DC-balanced AC-coupling capability, and side-channel telemetry compatibility in automotive navigation and industrial display links.
Technical Context
The ISL34340INZ-T13 implements a 30× PCLK_IN serial multiplier with 8b/10b line coding to achieve 1.2Gbps raw serial rate for 24-bit RGB video. Its CDR recovers clock from the serial stream using REF_CLK fed into PCLK_IN, with ±5000ppm frequency offset tolerance and <10ps differential skew.
It integrates dual-role functionality: when VIDEO_TX = 1, RGBA/B/C pins act as LVCMOS inputs and SERIOP/SERION as high-speed outputs; when VIDEO_TX = 0, those pins reverse roles. Side-channel bidirectional data is embedded in vertical blanking intervals without bandwidth overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCLK_IN Frequency | 6–40MHz: supports WSVGA 1024×600 @ 60fps (8% blanking) and SVGA 800×600 @ 70fps (16% blanking) |
| Serial Data Rate | 1.2Gbps (30× PCLK_IN): enables 24-bit RGB transport over one differential pair with no parallel clock forwarding |
| Line Coding | DC-balanced 8b/10b: permits AC-coupling via 27nF capacitors and eliminates ground-shift sensitivity |
| Differential Termination | Internal 100Ω: eliminates need for external resistors unless side-channel is disabled |
| ESD Rating | 8kV on SERIOP/SERION (HBM): meets robustness requirements for automotive and industrial cable interfaces |
| Supply Voltages | 1.8V (VDD_CDR/VDD_CR) and 3.3V (VDD_IO/VDD_TX/VDD_P/VDD_AN): requires strict 3.3V-before-1.8V power sequencing |

| REF_RES (Pin 36) | Analog bias reference | Connects to 3.16kΩ ±1% resistor to GND to set internal analog bias currents |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar video SERDES applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL34341 | Pin-compatible upgrade with improved jitter performance (0.3% RMS PCLK_OUT jitter), extended temperature range (-40°C to +105°C), and enhanced ESD (15kV HBM on SERIO) | Recommended for new designs requiring higher reliability in extended-temp environments (e.g., under-hood automotive) | Select ISL34341 when designing for production after June 2008; ISL34340INZ-T13 is NOT RECOMMENDED FOR NEW DESIGNS per FN6255.1. |
| MAX9205 | 24-bit serializer only (no deserializer function); uses 7-bit encoding; lacks side-channel; requires external termination | Suitable for unidirectional camera-to-processor links where remote configuration is unnecessary | Choose MAX9205 only if system architecture mandates fixed serializer-only topology and side-channel is unused. |
Compared with ISL34340INZ-T13, ISL34341 offers lower jitter and wider temperature support for new designs, while MAX9205 provides simpler unidirectional serialization but forfeits bidirectional side-channel and dual-role flexibility-making ISL34340INZ-T13 uniquely suited for legacy bidirectional WSVGA links where part reuse is critical.

FAQ
What is the maximum supported pixel clock frequency for ISL34340INZ-T13?
The ISL34340INZ-T13 supports PCLK_IN frequencies from 6MHz to 40MHz. At 40MHz, it delivers WSVGA 1024×600 resolution at 60fps with 8% vertical blanking, enabling high-fidelity video transport over a single differential pair without compromising timing margins.
How does the ISL34340INZ-T13 handle bidirectional communication?
The ISL34340INZ-T13 embeds bidirectional auxiliary data in the vertical blanking interval using its side-channel feature. This occurs without additional bandwidth or pins-data flows concurrently with video on the same SERIOP/SERION differential pair, controlled via I²C registers and synchronized to frame boundaries.
Can ISL34340INZ-T13 operate with AC-coupled differential signaling?
Yes, the ISL34340INZ-T13 supports AC-coupling via 27nF capacitors on SERIOP and SERION due to its DC-balanced 8b/10b line coding. This eliminates ground potential differences between endpoints and is essential for reliable operation across long cables in electrically noisy environments.
What is the purpose of the VIDEO_TX pin on ISL34340INZ-T13?
The VIDEO_TX pin (Pin 49) determines operational mode: logic HIGH configures ISL34340INZ-T13 as a serializer (parallel-to-serial), while logic LOW configures it as a deserializer (serial-to-parallel). This dual-role capability simplifies inventory and enables identical hardware at both ends of the link.
Does ISL34340INZ-T13 require external termination resistors?
No-ISL34340INZ-T13 integrates 100Ω differential termination on SERIOP/SERION pins. External termination is prohibited unless the side-channel is disabled, as stated in the datasheet. This simplifies PCB layout and improves signal integrity consistency across production units.
