Product details
Overview
DS92LV0422SQ/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 + clock for RGB-style display interfaces. It supports 10–75 MHz pixel clocks, 24-bit color depth, and operates with 1.8-V or 3.3-V I/O. Used in frame grabbers, medical imaging systems, and industrial displays requiring long-cable AC-coupled interconnects up to 10 m.
For engineers reviewing the DS92LV0422SQ/NOPB datasheet, DS92LV0422SQ/NOPB pinout, DS92LV0422SQ/NOPB application, or DS92LV0422SQ/NOPB equivalent, key selection criteria include its CML-to-LVDS conversion capability, programmable receiver equalization (EQ), LOCK status output, spread-spectrum clocking (SSCG), and compatibility with DS92LV0421 serializer in embedded video links.
Technical Context
The DS92LV0422SQ/NOPB implements a fully self-clocked deserialization architecture with no external reference clock required - it achieves fast random-data lock using embedded clock recovery. Its CML input stage includes configurable equalization gain (1.625 dB or ~13 dB via EQ pin), supporting lossy STP cables up to 10 m.
Internally, the device reconstructs a parallel Channel Link LVDS interface (4 data + 1 clock lanes) with selectable MSB/LSB mapping (MAPSEL), output voltage control (VODSEL = ±250 mV or ±400 mV), and flexible power-down (PDB) and output enable (OEN) logic. SSCG is supported across 10–65 MHz via SSC[2:0] pins with LFMODE-selectable frequency bands.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Clock Range | 10 MHz to 75 MHz - defines supported pixel rates for QVGA to XGA RGB displays |
| Input Interface | CML serial pair (RIN+/−) - enables AC-coupled, low-EMI transmission over 100-Ω STP cable |
| Output Interface | 5-lane Channel Link LVDS (TXOUT[3:0]± + TXCLKOUT±) - directly drives standard OpenLDI-compatible display controllers |
| Supply Voltages | VDDTX = 3.3 V ±10% (LVDS outputs); VDDIO = 1.8 V or 3.3 V ± tolerance - dual-rail I/O flexibility for mixed-voltage systems |
| Equalization Gain | Configurable via EQ pin: ~1.625 dB (EQ = 0) or ~13 dB (EQ = 1) - adapts to cable loss without firmware |
| ESD Rating | >±8 kV HBM on RIN+/− - robust protection for industrial and medical field-deployed video links |
| Operating Temp | −40°C to +85°C - qualified for extended-temperature industrial and automotive cabin applications |
Pinout & Package
DS92LV0422SQ/NOPB uses a 48-pin WQFN package (7.0 mm × 7.0 mm, 0.5-mm pitch) with exposed thermal pad (DAP) requiring ≥9 vias to ground plane for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RIN+/RIN− | CML serial data input pair | AC-coupled differential input accepting serialized video stream; requires 0.1-µF coupling caps |
| TXCLKOUT+/− | LVDS clock output pair | Reconstructed pixel clock output; must be terminated with 100-Ω differential load |
| TXOUT[3:0]+/− | LVDS data output lanes | 4-lane parallel video bus (24-bit RGB + 3-bit control); each lane requires 100-Ω termination |
| LOCK | LVCMOS status output | Active-high signal indicating PLL lock - used for system readiness detection and fault monitoring |
| OEN | LVCMOS output enable | Controls tri-state behavior of all LVDS outputs - enables hot-plug and power sequencing |
| EQ (PASS) | Strap pin for receiver gain | Direct hardware-selectable equalization: EQ = 1 enables ~13 dB boost for long-cable operation |
| CONFIG[1:0] | Mode configuration inputs | Selects interfacing partner (e.g., DS92LV0421, DS90UR241) and control filter settings |
| VODSEL | LVDS output swing select | VODSEL = 1 → ±400 mV (800 mVp-p) for noise immunity; VODSEL = 0 → ±250 mV (500 mVp-p) for low-power mode |
Key Features
| Feature | Design Value |
|---|---|
| Self-clocked deserialization | No external reference clock needed - reduces BOM count and board routing complexity in display subsystems |
| Hardware-configurable EQ gain | Two-level receiver equalization (1.625 dB / ~13 dB) set by single EQ pin - eliminates need for register programming during boot |
| Spread-spectrum clocking (SSCG) | SSC[2:0] + LFMODE pins enable EMI reduction across 10–65 MHz - critical for FCC/CE compliance in medical and office equipment |
| Tri-state LVDS outputs | OEN and PDB jointly control output driver state - supports safe hot-swap, power sequencing, and multi-drop bus sharing |
| Robust 10-m cable support | Integrated CML receiver + configurable EQ + DC-balanced serialization enables reliable 100-Ω STP transmission up to 10 meters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS92LV2422 | Same Channel Link II protocol, but supports only 1.8-V LVDS outputs (no 3.3-V option); lacks SSCG and EQ strap pin | Best suited for low-power, short-cable (<3 m), fixed-frequency designs where EMI reduction is not required | Choose DS92LV2422 only if VDDTX = 1.8 V is acceptable and spread-spectrum or adaptive EQ is unnecessary |
| DS90UR241 | Supports higher data rates (up to 1.5 Gbps), includes integrated HDCP engine and MIPI D-PHY output; requires I²C configuration | Targeted at premium displays and automotive infotainment with content protection and mobile interface needs | Choose DS90UR241 when HDCP, higher bandwidth, or MIPI output are mandatory - not a drop-in replacement |
Compared with DS92LV2422 and DS90UR241, DS92LV0422SQ/NOPB uniquely balances industrial ruggedness (8-kV HBM), hardware-strapped configurability (EQ, SSCG, VODSEL), and dual-voltage LVDS outputs - making it optimal for cost-sensitive, long-cable, non-HDCP display links requiring zero-software bring-up.

FAQ
What is the primary function of the DS92LV0422SQ/NOPB in a video interface system?
The DS92LV0422SQ/NOPB functions as a Channel Link II deserializer that recovers pixel clock and video data from a high-speed CML serial stream and outputs them as a standard 5-lane LVDS parallel interface (4 data + 1 clock). It enables seamless migration from wide parallel LVDS buses to compact, low-EMI serial links - a core capability of the DS92LV0422SQ/NOPB in display and imaging systems.
Does the DS92LV0422SQ/NOPB require an external reference clock to operate?
No, the DS92LV0422SQ/NOPB does not require an external reference clock. It performs self-clocked deserialization using embedded clock recovery from the incoming CML data stream. This eliminates clock distribution complexity and makes the DS92LV0422SQ/NOPB ideal for plug-and-play video links where timing synchronization must be autonomous.
How is receiver equalization configured on the DS92LV0422SQ/NOPB?
Receiver equalization on the DS92LV0422SQ/NOPB is configured via the EQ (also labeled PASS) strap pin: EQ = 1 enables ~13 dB gain for long-cable (>5 m) operation, while EQ = 0 sets ~1.625 dB gain for short-cable use. This hardware-selectable setting requires no register writes and is active immediately after power-up - a defining feature of the DS92LV0422SQ/NOPB's robustness.
What are the supported supply voltages for DS92LV0422SQ/NOPB LVDS outputs?
DS92LV0422SQ/NOPB supports dual-voltage LVDS outputs: VDDTX must be 3.3 V ±10% to drive the TXOUT[3:0]± and TXCLKOUT± lanes, while VDDIO may be either 1.8 V ±5% or 3.3 V ±10% for LVCMOS control pins. This separation allows the DS92LV0422SQ/NOPB to interface with both low-voltage logic and legacy 3.3-V display timing controllers.
Can the DS92LV0422SQ/NOPB be used with the DS92LV0421 serializer?
Yes, the DS92LV0422SQ/NOPB is fully interoperable with the DS92LV0421 serializer as part of the same Channel Link II chipset. Their pin configurations, timing protocols, and register maps are aligned - enabling direct integration in point-to-point video links. The DS92LV0422SQ/NOPB's CONFIG[1:0] pins must be set to '00' or '01' to match DS92LV0421 operation.
