Product details
Overview
DS92LV2412SQ/NOPB from Texas Instruments is a Channel Link II deserializer IC that converts a single high-speed CML serial stream (5–50 MHz pixel clock) into a 24-bit LVCMOS parallel video interface with 3-bit control signals. It supports RGB888 display timing, AC-coupled STP cable up to 10 m, and operates at 1.8 V or 3.3 V I/O voltage. Used in embedded display links between ASIC/FPGA and LCD panels.
For engineers reviewing the DS92LV2412SQ/NOPB datasheet, DS92LV2412SQ/NOPB pinout, DS92LV2412SQ/NOPB application, or DS92LV2412SQ/NOPB equivalent, key selection criteria include its random-data lock capability (no reference clock required), LOCK status reporting, configurable input equalization, spread spectrum clock generation, and support for BIST link integrity validation.
Technical Context
The DS92LV2412SQ/NOPB implements a fully autonomous CML receiver with adaptive equalization across four EQ settings, enabling robust operation over lossy 100 Ω STP cables. Its PLL locks directly to incoming serialized data without external timing references - eliminating sync-pattern dependencies and supporting true hot-plug operation.
It integrates dual-mode I²C and strap-pin configuration, real-time LOCK output for system synchronization, and programmable slew rate control on CLKOUT and DO[23:0] outputs. The device supports AT-speed BIST with PASS reporting and offers selectable SSCG frequency bands (5–20 MHz or 20–50 MHz) via LF_MODE and SSC[3:0] straps.
Key Specifications

FAQ
What is the primary function of DS92LV2412SQ/NOPB in a video interface system?
The DS92LV2412SQ/NOPB functions as a Channel Link II deserializer that recovers a high-speed CML serial stream and reconstructs it into a synchronous 24-bit LVCMOS RGB888 parallel interface with DE/HS/VS control signals and a pixel clock. It enables reliable, low-EMI video transmission over 100 Ω STP cables up to 10 meters without requiring an external reference clock - a core capability of DS92LV2412SQ/NOPB.
Does DS92LV2412SQ/NOPB require an external reference clock to operate?
No, DS92LV2412SQ/NOPB does not require an external reference clock. Its PLL achieves random-data lock directly from the incoming serialized bitstream, enabling true "plug-and-go" and hot-plug operation. This autonomous locking behavior is intrinsic to DS92LV2412SQ/NOPB and eliminates dependency on separate clock distribution networks or training sequences.
How is the LOCK pin used in DS92LV2412SQ/NOPB applications?
The LOCK pin on DS92LV2412SQ/NOPB provides real-time indication of PLL lock status: HIGH when locked and outputs are valid, LOW when unlocked and outputs are in sleep state (controlled by OSS_SEL). System firmware uses DS92LV2412SQ/NOPB LOCK to gate video enable signals or trigger frame capture - ensuring deterministic timing without software polling.
Can DS92LV2412SQ/NOPB operate with both 1.8 V and 3.3 V LVCMOS I/O levels?
Yes, DS92LV2412SQ/NOPB supports dual-voltage LVCMOS I/O operation: VDDIO may be supplied at either 1.8 V ±5% or 3.3 V ±10%. This flexibility allows direct interfacing with both low-power FPGAs and legacy 3.3 V display controllers without level-shifting circuitry - a key interoperability feature of DS92LV2412SQ/NOPB.
What is the purpose of the BISTEN and PASS pins on DS92LV2412SQ/NOPB?
The BISTEN pin enables built-in self-test mode on DS92LV2412SQ/NOPB when asserted high (with REG=0), initiating AT-speed link validation using a checkerboard pattern. The PASS pin then reports test result: HIGH indicates error-free transmission, LOW indicates detected bit errors. This hardware-level diagnostics capability is unique to DS92LV2412SQ/NOPB and supports in-system validation without host processor involvement.
