Texas Instruments DS92LV2412SQX/NOPB

Overview

DS92LV2412SQX/NOPB from Texas Instruments is a Channel Link II deserializer IC that converts a single high-speed CML serial stream with embedded clock into a 24-bit LVCMOS parallel interface plus 3-bit control signals, supporting 5–50 MHz pixel clocks and up to 1.2 Gbps payload for RGB888 video transport over AC-coupled STP or coaxial cables.

For engineers reviewing the DS92LV2412SQX/NOPB datasheet, DS92LV2412SQX/NOPB pinout, DS92LV2412SQX/NOPB application, or DS92LV2412SQX/NOPB equivalent, key selection considerations include its 60-pin WQFN package, 1.8 V/3.3 V I/O compatibility, programmable receiver equalization, LOCK status reporting, and BIST-enabled link integrity validation in display and imaging systems.

Technical Context

The DS92LV2412SQX/NOPB operates as the deserializing half of a bidirectional Channel Link II chipset paired with DS92LV2411, using CML input receivers (RIN+/RIN−) with adjustable equalization and LVCMOS outputs (DO[23:0], CO1–CO3, CLKOUT) with configurable slew rate and output sleep state. It achieves random-data lock without external reference clock or sync patterns.

Its architecture integrates on-chip DC-balancing, scrambling, spread spectrum clock generation (SSCG), and AT-speed BIST with PASS/LOCK reporting pins-enabling plug-and-play operation in hot-plug video links while minimizing EMI via CML signaling, drive strength control, and SSCG.

FAQ

What is the primary function of DS92LV2412SQX/NOPB in a video system?

The DS92LV2412SQX/NOPB acts as a deserializer that converts a single high-speed Channel Link II CML serial stream-including embedded clock and 24-bit RGB + 3-bit control data-into parallel LVCMOS signals for direct connection to an FPGA, ASIC, or display controller. It reconstructs the pixel clock and provides real-time LOCK status, enabling deterministic video timing without external clock distribution.

Does DS92LV2412SQX/NOPB require an external reference clock to lock?

No, DS92LV2412SQX/NOPB achieves random-data lock autonomously without any external reference clock or special sync patterns. Its internal PLL locks directly to the incoming serial data stream, enabling true "plug-and-go" and hot-plug operation-critical for medical endoscopes and field-deployable surveillance cameras where clock handshaking is impractical.

How does DS92LV2412SQX/NOPB support long cable runs?

DS92LV2412SQX/NOPB supports up to 10 m STP or 20+ m coaxial cable runs via programmable receiver equalization (EQ[3:0]), AC-coupled CML inputs (RIN+/RIN−) with 0.1 µF series capacitors, and optional transmit de-emphasis on the serializer side. Its design targets lossy channels typical in industrial and medical cabling environments.

Can DS92LV2412SQX/NOPB operate with both 1.8 V and 3.3 V I/O voltages?

Yes, DS92LV2412SQX/NOPB supports dual-voltage LVCMOS I/O: VDDIO accepts either 1.8 V ±5% or 3.3 V ±10%, allowing seamless interfacing with both low-voltage FPGAs and legacy 3.3 V display controllers without level-shifting circuitry.

What is the purpose of the LOCK and PASS pins on DS92LV2412SQX/NOPB?

The LOCK pin is an active-high real-time indicator that the internal PLL has achieved stable lock to the incoming serial stream-used for system readiness signaling and video blanking control. The PASS pin reports BIST test results: high indicates error-free transmission during AT-speed self-test, providing hardware-validated link integrity without software intervention.
