Product details
Overview
DS92LV0421SQ/NOPB from Texas Instruments is a Channel Link II serializer IC that converts 24-bit RGB video + 3-bit control (5-channel LVDS parallel interface) into a high-speed CML serial stream over a single AC-coupled STP pair. It operates from 10 MHz to 75 MHz pixel clock, supports 1.8 V or 3.3 V LVCMOS I/O, integrates DC-balancing and data scrambling, and targets embedded display interconnects up to 10 m.
For engineers reviewing the DS92LV0421SQ/NOPB datasheet, DS92LV0421SQ/NOPB pinout, DS92LV0421SQ/NOPB application, or DS92LV0421SQ/NOPB equivalent, key selection criteria include its 5-channel LVDS-to-CML serialization capability, programmable VOD (±300 mV / ±450 mV), de-emphasis control, integrated BIST, and compatibility with QVGA–XGA RGB-style displays in space-constrained industrial and medical systems.
Technical Context
The DS92LV0421SQ/NOPB implements a full Channel Link II serializer with embedded clock architecture-no external reference clock required at the deserializer side. Its parallel interface accepts standard OpenLDI/Channel Link LVDS inputs (RXCLKIN±, RXIN[3:0]±) with 100-Ω termination, while its serial output (DOUT±) uses CML signaling with AC coupling and selectable output voltage swing.
It features pin- and register-configurable modes including MAPSEL for MSB/LSB mapping, CONFIG[1:0] for interoperability with DS92LV2422/DS90UR124/DS90C124, and VODSEL/DE-EMPH for optimizing signal integrity on lossy cables. Built-in at-speed BIST and LOCK status reporting enable system-level diagnostics without host processor intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS92LV2421 | Legacy Channel Link serializer; no DC-balancing, no scrambling, fixed 1.2-V VOD, no de-emphasis | Limited to shorter cables (<3 m); higher EMI; requires external clock at deserializer | Choose only if backward compatibility with legacy DS92LV2422 deserializer is mandatory and cable length <2 m |
| DS90UB925QSQ | FPD-Link III serializer; 1.5-Gbps max, integrated HDCP, 1.8-V only, different pinout and protocol stack | Targets automotive infotainment; requires FPD-Link III deserializer and HDCP licensing | Select for new automotive designs needing security and higher bandwidth; not drop-in compatible |
Compared with DS92LV2421 and DS90UB925QSQ, DS92LV0421SQ/NOPB uniquely balances industrial robustness (±8-kV HBM, −40°C to +85°C), long-cable capability (10 m STP), and protocol flexibility (CONFIG[1:0]-driven interoperability) without requiring system-level redesign or licensing.

FAQ
What is the maximum supported cable length for DS92LV0421SQ/NOPB?
The DS92LV0421SQ/NOPB supports AC-coupled STP cable runs up to 10 meters when used with appropriate de-emphasis and receiver equalization settings. This specification assumes 100-Ω characteristic impedance, typical loss characteristics of Category-rated shielded twisted-pair, and operation within the 10–75 MHz pixel clock range. Cable performance must be validated per application environment.
Does DS92LV0421SQ/NOPB require an external reference clock at the deserializer side?
No, DS92LV0421SQ/NOPB does not require an external reference clock at the deserializer side. Its Channel Link II architecture embeds clock information within the serial bitstream, enabling the companion deserializer (e.g., DS92LV0422) to recover timing autonomously-a key advantage over legacy Channel Link I and parallel clock schemes.
Can DS92LV0421SQ/NOPB operate with both 1.8 V and 3.3 V I/O supplies simultaneously?
Yes, DS92LV0421SQ/NOPB supports dual-voltage operation: VDDIO may be set to either 1.8 V ±5% or 3.3 V ±10%, while internal core supplies (VDDHS, VDDL, VDDP, VDDRX, VDDTX) all operate at 1.8 V ±5%. This allows seamless interfacing with both 1.8-V and 3.3-V logic domains without level shifters.
How is BIST functionality enabled and verified on DS92LV0421SQ/NOPB?
BIST is enabled by asserting the BISTEN pin high. When active, DS92LV0421SQ/NOPB generates a known pseudo-random test pattern and transmits it serially. The companion deserializer validates the received data and asserts its PASS pin high if no errors are detected. DS92LV0421SQ/NOPB itself does not provide local PASS feedback-it relies on deserializer-side reporting.
What is the purpose of the CONFIG[1:0] pins on DS92LV0421SQ/NOPB?
The CONFIG[1:0] pins configure DS92LV0421SQ/NOPB's interoperability mode: 00/01 selects DS92LV2422 or DS92LV0422 deserializers (with optional control-signal filtering), 10 selects DS90UR124/DS99R124Q-Q1, and 11 selects DS90C124. This enables hardware-selectable protocol mapping without firmware changes.
