Product details
Overview
DS90CR482VSX/NOPB from Texas Instruments is a 48-bit LVDS deserializer IC that converts eight serialized LVDS data streams and one LVDS clock into parallel LVCMOS/TTL data outputs. It operates at input clock frequencies from 65 MHz to 112 MHz, delivers up to 5.376 Gbits/sec throughput, supports cable deskew of ±1 LVDS bit time (up to 80 MHz), and features DC balance encoding and pre-emphasis compatibility for long-cable applications in industrial display interfaces.
For engineers reviewing the DS90CR482VSX/NOPB datasheet, DS90CR482VSX/NOPB pinout, DS90CR482VSX/NOPB application, or DS90CR482VSX/NOPB equivalent, key selection criteria include deskew capability under DC-balance mode, LVDS receiver jitter tolerance (<100 ps cycle-to-cycle), RSKMD margin compliance for >5 m cables, and compatibility with DS90CR481 transmitter in point-to-point Channel Link systems.
Technical Context
The DS90CR482VSX/NOPB implements a PLL-based LVDS receiver architecture synchronized to an incoming LVDS clock, reconstructing 48-bit parallel data with programmable deskew alignment per channel. Its internal strobe positioning logic dynamically adjusts sampling points across eight differential inputs using a 1/3-bit-time step size over ±1 TBIT range when DESKEW = HIGH and BAL = HIGH on the companion DS90CR481.
It requires external configuration via DESKEW and DS_OPT pins to initiate calibration; during deskew training, all outputs hold LOW while RxCLK remains active. The receiver rejects inter-symbol interference through optional DC balance decoding and maintains timing integrity via tight setup/hold windows (e.g., RSRC = 2.4 ns at 112 MHz) and low propagation latency (RPDL = 3×TCIP + 4.0 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Clock Range | 65–112 MHz: defines maximum parallel data rate (672 Mbps per LVDS lane at 112 MHz) |
| Data Throughput | 5.376 Gbits/sec at 112 MHz: enables high-resolution video transmission over compact differential cabling |
| Cable Deskew Range | ±1 LVDS bit time (up to 80 MHz): compensates pair-to-pair skew in cables ≥5 m without external FPGA logic |
| Supply Voltage | +3.3 V (3.0–3.6 V): compatible with standard industrial LDOs and avoids level-shifting in mixed-voltage systems |
| Receiver Skew Margin (RSKMD) | ≥25% of TBIT with deskew: ensures reliable sampling under combined ISI, TPPOS variance, and TJCC jitter |
| Power-Down Current | 20–100 µA: reduces system standby power when interface is inactive but supply remains active |
| LVDS Input Threshold | VTH = +100 mV, VTL = −100 mV: provides noise immunity against common-mode disturbances on long traces |
Pinout & Package
DS90CR482VSX/NOPB is housed in a 100-pin TQFP (VS package) with exposed thermal pad, optimized for flow-through routing and thermal dissipation in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RxIN0+ / RxIN0− to RxIN7+ / RxIN7− | LVD differential data inputs | Accept eight serialized LVDS data lanes; require 100 Ω termination at receiver end |
| RxCLK+ / RxCLK− | LVD differential clock input | Synchronizes internal PLL and data recovery; determines maximum throughput and deskew validity |
| DESKEW | Deskew enable control | High = activate automatic deskew calibration; must be asserted after PLL lock and before data transfer |
| PD | Power-down control | High = normal operation; Low = reduce ICCR to µA range and force outputs LOW |
| RxOUT0–RxOUT47 | LVCMOS/TTL parallel data outputs | 48-bit wide CMOS/TTL outputs with 2 ns transition times; driven LOW during power-down |
| RxCLKOUT | Recovered clock output | Provides synchronous clock for downstream logic; remains active during deskew and power-down modes |
Key Features
| Feature | Design Value |
|---|---|
| Cable deskew calibration | Adjusts sampling strobes per channel by ±1 bit time in 0.3 TBIT steps-enables robust operation over 5+ meter shielded twisted-pair cables |
| DC balance decoding support | Processes DCBAL-encoded data from DS90CR481 to minimize baseline wander and extend eye opening on lossy media |
| Low-jitter clock recovery | Rejects <100 ps cycle-to-cycle input jitter; preserves timing margin for downstream logic synchronization |
| Flow-through pinout | Input pins on one side, outputs on opposite side-reduces layer count and trace length in high-speed PCB routing |
| 3.3 V single-supply operation | Eliminates need for dual-rail supplies or level shifters in modern embedded display subsystems |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90CR288VSX/NOPB | 28-bit deserializer, no deskew, max 85 MHz clock, lower power (140 mA vs 280 mA) | Suitable only for shorter cables (<3 m) and narrower buses (e.g., 24-bit RGB + sync) | Select when bandwidth and cable length requirements are reduced and deskew is unnecessary. |
| SN65LVDS32PW | Single-channel LVDS receiver, no serialization/deserialization, no deskew or DC balance | Used for point-to-point clock/data recovery only-not for multi-lane parallel bus reconstruction | Choose only for simple LVDS signal conditioning where 48-bit deserialization is handled elsewhere. |

FAQ
What is the maximum cable length supported by DS90CR482VSX/NOPB?
The DS90CR482VSX/NOPB supports cables ≥5 meters in length when used with its companion DS90CR481 transmitter, enabled DC balance mode, and appropriate pre-emphasis setting. This capability relies on the integrated deskew function (±1 LVDS bit time), DC balance encoding to suppress ISI, and pre-emphasis to counteract cable attenuation-verified per TI's SNLS137D datasheet testing with shielded twisted-pair media.
Does DS90CR482VSX/NOPB require external termination resistors?
Yes, DS90CR482VSX/NOPB requires a 100 Ω differential termination resistor placed as close as possible to its RxIN and RxCLK input pins. This resistor matches standard twisted-pair cable impedance, minimizes reflections, completes the LVDS current loop, and is mandatory for signal integrity-per TI's recommended layout guidelines in SNLS137D Section "CABLE TERMINATION".
How does the deskew function work in DS90CR482VSX/NOPB?
The deskew function in DS90CR482VSX/NOPB operates only when DESKEW = HIGH and the companion DS90CR481 has BAL = HIGH. It calibrates sampling strobes per LVDS data channel using a 1/3-bit-time step size over ±1 TBIT range, correcting fixed pair-to-pair skew up to 80 MHz clock rates. During calibration, all RxOUT pins drive LOW while RxCLKOUT remains active-requiring DS_OPT assertion on the transmitter for ≥4 clock cycles.
Can DS90CR482VSX/NOPB operate without DC balance encoding?
Yes, DS90CR482VSX/NOPB can receive data from DS90CR481 in non-DC-balance mode (BAL = LOW), supporting backward compatibility with legacy 21- and 28-bit Channel Link receivers. However, deskew functionality is disabled in this mode, and ISI mitigation relies solely on pre-emphasis-limiting reliable operation to shorter cables (<3 m) per TI's SNLS137D APPLICATIONS INFORMATION section.
What is the power consumption of DS90CR482VSX/NOPB at 112 MHz?
At 112 MHz with DC balance enabled, DS90CR482VSX/NOPB draws 250–280 mA typical supply current (ICCRW), corresponding to ~0.825–0.924 W at 3.3 V. In power-down mode (PD = LOW), current drops to 20–100 µA. These values are specified in the "RECEIVER SUPPLY CURRENT" table of SNLS137D and assume worst-case pattern loading and 3.3 V supply.
