Product details
Overview
DS90CR483AVJD/NOPB from Texas Instruments is a 48-bit LVDS serializer IC that converts parallel CMOS/TTL data into eight serialized LVDS data streams plus one LVDS clock channel, supporting input clock frequencies from 33 MHz to 112 MHz and delivering up to 5.38 Gbits/sec bandwidth. It features pre-emphasis, DC-balanced transmission, and flow-through pinout, and is used in high-speed video interconnects such as flat-panel display interfaces over long cables.
For engineers reviewing the DS90CR483AVJD/NOPB datasheet, DS90CR483AVJD/NOPB pinout, DS90CR483AVJD/NOPB application, or DS90CR483AVJD/NOPB equivalent, this page delivers verified electrical specs, cable deskew behavior, transmitter jitter rejection, LVDS output compliance, and real-world design implications for EMI-sensitive, long-cable digital video links.
Technical Context
The DS90CR483AVJD/NOPB implements a PLL-based serialization architecture with user-selectable pre-emphasis (via PRE pin voltage) and cycle-to-cycle DC balancing (enabled by BAL = HIGH). Its transmitter rejects cycle-to-cycle jitter at the input clock and maintains <100 ps worst-case output jitter, enabling robust sampling at the receiver end.
It operates exclusively in point-to-point configuration with mandatory 100 Ω differential termination at the receiver. Cable deskew is supported only when DC balancing is active and clock rates are ≤80 MHz, with ±1 LVDS bit-time skew correction capability and 0.3 TBIT step resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Clock Range | 33–112 MHz - defines maximum parallel data throughput; at 112 MHz, achieves 672 Mbps per LVDS lane and 5.38 Gbps total bandwidth. |
| Supply Voltage | +3.3 V (3.0–3.6 V range) - requires stable low-noise rail; supply noise must be ≤100 mVp-p to maintain jitter performance. |
| Differential Output Voltage (VOD) | 250–450 mV - meets ANSI/TIA/EIA-644-1995 LVDS standard; ensures signal integrity across 100 Ω differential loads. |
| Transmitter Jitter (TJCC) | <100 ps cycle-to-cycle - enables reliable RSKM/RSKMD margin calculation; critical for >5 m cable operation. |
| Cable Deskew Range | ±1 LVDS bit time (up to 80 MHz) - corrects pair-to-pair skew in shielded twisted-pair cabling; requires DESKEW=HIGH and DS_OPT calibration sequence. |
| DC Balance Support | Enabled when BAL = HIGH - reduces ISI and baseline wander on long cables; required for deskew functionality and compatibility with DS90CR484A receiver. |
| Pre-emphasis Control | Voltage-controlled via PRE pin (0.75 V to VCC) - adjusts dynamic drive strength to counteract high-frequency cable loss; 1.5 V setting typical for 5 m @ 112 MHz. |
Pinout & Package
DS90CR483AVJD/NOPB is housed in a 100-lead TQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin numbering follows standard counter-clockwise convention starting from top-left corner (Pin 1 marked).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TxIN[0:47] | Parallel CMOS/TTL Data Inputs | 48-bit wide synchronous bus accepting 3.3 V logic; 5 V tolerant - allows direct interface to legacy 5 V controllers without level shifters. |
| TxCLK IN | Input Reference Clock | Single-ended CMOS/TTL clock input; falling edge triggers PLL sampling - requires <3 ns transition time and 35–65% duty cycle. |
| BAL | DC Balance Enable | Active-HIGH control; enables cycle-to-cycle disparity encoding - mandatory for deskew and long-cable ISI reduction. |
| PRE | Pre-emphasis Level Select | Analog voltage input (0.75 V–VCC) setting dynamic current boost during LVDS transitions - determines cable reach and eye opening. |
| DS_OPT | Deskew Calibration Trigger | Active-LOW signal initiating receiver deskew training sequence - must be held low ≥4 clock cycles before data transfer resumes. |
| PD | Power-Down Control | Active-HIGH input disabling PLL and placing LVDS outputs in TRI-STATE - reduces supply current to <50 µA. |
| TxOUT[0:7] | LVDS Serialized Data Outputs | Eight differential pairs carrying 48-bit multiplexed payload - each pair supports 672 Mbps at 112 MHz; requires 100 Ω termination at receiver. |
| TxCLK OUT | LVDS Clock Output | Ninth LVDS differential pair transmitting phase-aligned clock - essential for synchronous deserialization at DS90CR484A receiver. |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout | Minimizes PCB trace length mismatch between parallel inputs and LVDS outputs - simplifies layout and preserves timing margins for 48-bit bus routing. |
| 5 V tolerant TxIN pins | Eliminates need for external level translators when interfacing with 5 V microcontrollers or FPGAs - reduces BOM count and signal integrity risk. |
| Transmitter jitter rejection | Reduces impact of noisy or low-quality input clocks on output eye diagram - enables use of cost-effective crystal oscillators instead of ultra-low-jitter sources. |
| LVDS compliance (ANSI/TIA/EIA-644) | Guarantees interoperability with industry-standard LVDS receivers and cables - avoids proprietary signaling constraints in system integration. |
| Pre-emphasis + DC balance co-optimization | Together suppress both frequency-dependent attenuation and baseline wander - extends usable cable length beyond 5 meters with low BER in display applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90CR483AQMA/NOPB | Same electrical specs and pinout; QMA variant rated for −40°C to +105°C industrial temp range vs. −10°C to +70°C for DS90CR483AVJD/NOPB. | Suitable for extended-temperature avionics or automotive head-up displays where ambient exceeds +70°C. | Select DS90CR483AQMA/NOPB when operating temperature exceeds +70°C; otherwise DS90CR483AVJD/NOPB is optimal for commercial display systems. |
| SN65LVDS32 | 28-bit serializer only; no DC balance, pre-emphasis, or deskew; max clock 85 MHz; 32-pin TSSOP package. | Limited to shorter-reach, lower-bandwidth links (e.g., internal PCB traces or ≤2 m cables); lacks cable compensation features. | Choose SN65LVDS32 only for cost-sensitive, short-distance applications where full 48-bit bandwidth and long-cable robustness are unnecessary. |
Compared with DS90CR483AQMA/NOPB, DS90CR483AVJD/NOPB trades extended temperature range for lower cost and same core functionality; compared with SN65LVDS32, it delivers double data width, higher clock support, and advanced cable-compensation features essential for >3 m video links.

FAQ
What is the maximum cable length supported by DS90CR483AVJD/NOPB?
The DS90CR483AVJD/NOPB supports cables exceeding 5 meters when used with appropriate pre-emphasis (e.g., 1.5 V at 112 MHz) and DC balancing enabled. Performance depends on cable type, impedance match, and clock rate - shielded twisted-pair media with 100 Ω characteristic impedance yields best results. At 80 MHz with deskew active, ±1 bit-time correction accommodates up to ~12.5 ns skew, typical of 6+ meter runs.
Does DS90CR483AVJD/NOPB require external termination resistors?
Yes, DS90CR483AVJD/NOPB requires a 100 Ω differential termination resistor placed as close as possible to the receiver inputs (e.g., DS90CR484A), not at the DS90CR483AVJD/NOPB output. This matches standard LVDS media impedance, controls reflections, and completes the current loop. Mismatched termination causes signal integrity degradation and increased BER.
Can DS90CR483AVJD/NOPB operate without DC balancing enabled?
Yes, DS90CR483AVJD/NOPB can operate with DC balancing disabled (BAL = LOW), retaining pre-emphasis support and compatibility with older 21- and 28-bit Channel Link receivers. However, deskew functionality is unavailable in this mode, and ISI increases on long cables - DC balancing is recommended for any application exceeding 2 meters or operating above 66 MHz.
What is the function of the DS_OPT pin on DS90CR483AVJD/NOPB?
The DS_OPT pin on DS90CR483AVJD/NOPB initiates the deskew calibration sequence when driven LOW for at least four clock cycles. It triggers the transmitter to send a dedicated pattern enabling the DS90CR484A receiver to adjust its sampling strobes. DS_OPT must be HIGH during normal data transmission; incorrect timing or state causes failed deskew and data corruption.
Is DS90CR483AVJD/NOPB pin-compatible with earlier DS90CR483 variants?
Yes, DS90CR483AVJD/NOPB is fully pin-compatible and functionally backward-compatible with DS90CR483, but removes the auto-gear PLLSEL option - PLLSEL now selects only fixed low or high gear. This eliminates unintended gear shifts due to VCC fluctuations, improving reliability. Existing PCB layouts and firmware require no changes except optional PLLSEL pin reconfiguration.
