Texas Instruments DS92LV0422SQE/NOPB

Overview

DS92LV0422SQE/NOPB from Texas Instruments is a Channel Link II deserializer IC that converts high-speed CML serial data (1 pair) into 4-channel LVDS parallel video/data plus clock, supporting 24-bit color depth at 10–75 MHz pixel rates for RGB-style display interfaces. It operates with 3.3-V LVDS output drivers and 1.8-V/3.3-V configurable I/O, features adjustable input equalization, and locks to incoming data without external reference clock - enabling plug-and-play operation in frame grabbers and embedded displays.

For engineers reviewing the DS92LV0422SQE/NOPB datasheet, DS92LV0422SQE/NOPB pinout, DS92LV0422SQE/NOPB application, or DS92LV0422SQE/NOPB equivalent, key selection criteria include its 48-pin WQFN package, CML-to-LVDS conversion capability, 100-Ω differential termination requirement on TXOUT/TXCLKOUT, spread-spectrum clocking support, and compatibility with DS92LV0421 serializer in point-to-point video links.

Technical Context

The DS92LV0422SQE/NOPB implements a fully self-clocked deserialization architecture: it recovers embedded clock and data from a single AC-coupled CML serial stream using adaptive equalization (EQ gain selectable via PASS pin), then reconstructs a synchronous 5-channel Channel Link LVDS parallel bus (4 data + 1 clock). Its PLL requires no external reference and achieves random-data lock within microseconds.

Configuration is supported via strap pins (CONFIG[1:0], MAPSEL, VODSEL, LFMODE, SSC[2:0]) and optional I²C interface (SDA/SCL with ID[X] address select). Power domains are segregated: VDDTX = 3.3 V for LVDS outputs, VDDIO = 1.8 V or 3.3 V for control logic, and multiple 1.8-V rails (VDDL, VDDP, VDDA, VDDSC) for core, PLL, analog, and SSCG circuitry.

FAQ

What is the primary function of the DS92LV0422SQE/NOPB?

The DS92LV0422SQE/NOPB is a Channel Link II deserializer IC that receives a high-speed CML serial data stream over a single differential pair and reconstructs it into a 5-channel LVDS parallel interface (4 data + 1 clock). It operates without an external reference clock, supports 10–75 MHz pixel rates, and is used in RGB display interfaces, frame grabbers, and industrial cameras. The DS92LV0422SQE/NOPB enables compact, low-EMI video interconnects in space-constrained embedded systems.

Does the DS92LV0422SQE/NOPB require an external reference clock?

No, the DS92LV0422SQE/NOPB does not require an external reference clock. Its internal PLL recovers clock and data directly from the incoming CML serial bitstream, enabling true embedded-clock operation. This eliminates clock skew and routing complexity associated with separate clock lines. The LOCK pin indicates PLL lock status, and the DS92LV0422SQE/NOPB achieves random-data lock within microseconds - essential for plug-and-play video links.

What are the supply voltage requirements for DS92LV0422SQE/NOPB?

The DS92LV0422SQE/NOPB requires multiple dedicated supplies: VDDTX = 3.3 V ±10% powers the LVDS output drivers; VDDIO = 1.8 V ±5% or 3.3 V ±10% powers control logic and I/O buffers; and VDDL, VDDP, VDDA, VDDSC = 1.8 V ±5% supply core logic, PLL, analog circuits, and spread-spectrum clock generator respectively. All supplies must ramp monotonically within 1.5 ms; failure to meet this may require a capacitor on the PDB pin per TI SNLS325D Section 9.

How is the DS92LV0422SQE/NOPB configured - via pins or registers?

The DS92LV0422SQE/NOPB supports dual-mode configuration: critical functions (CONFIG[1:0], MAPSEL, VODSEL, LFMODE, SSC[2:0], PASS/EQ, OEN) are set via LVCMOS strap pins at power-up, while advanced settings (equalization fine-tuning, BIST control, register readback) use the optional I²C interface (SDA/SCL with ID[X] address select). Strap pins provide deterministic startup behavior; I²C enables dynamic reconfiguration and diagnostics during operation - both methods are validated in the DS92LV0422SQE/NOPB datasheet.

Is the DS92LV0422SQE/NOPB pin-compatible with other TI deserializers?

Yes, the DS92LV0422SQE/NOPB is pin-compatible and functionally interchangeable with DS92LV2422 in the same 48-pin WQFN (RHS) package - sharing identical pinout, register map, and electrical specifications. It is not pin-compatible with DS92LV0421 (serializer, 36-pin WQFN) or DS90UR241 (different feature set and pin assignment). For full system design, DS92LV0422SQE/NOPB pairs with DS92LV0421 or DS92LV2421 serializers to form a complete Channel Link II link.
