Product details
Overview
DS92LV3241TVS/NOPB from Texas Instruments is a 32-bit Channel Link II serializer IC that converts parallel LVCMOS data (20–85 MHz) into embedded-clock LVDS serial streams across 2 or 4 differential lanes, delivering up to 2.72 Gbps payload for industrial imaging and HD video transport over CAT-5 or FR-4 backplanes.
For engineers reviewing the DS92LV3241TVS/NOPB datasheet, DS92LV3241TVS/NOPB pinout, DS92LV3241TVS/NOPB application, or DS92LV3241TVS/NOPB equivalent, key selection criteria include dual/quad mode configuration via MODE pin, embedded clock recovery capability, integrated 100Ω LVDS termination, pre-emphasis control (PRE), and BIST-enabled link integrity validation.
Technical Context
The DS92LV3241TVS/NOPB implements a parallel-to-serial conversion architecture with on-chip DC-balanced encoding, data randomization, and selectable transmit pre-emphasis. Its PLL-based CDR synchronizes to TxCLKIN (20–50 MHz in dual mode; 40–85 MHz in quad mode) without requiring an external reference clock.
It supports AC-coupled point-to-point interconnects with internal 100Ω differential termination and delivers deterministic latency (e.g., 4.5×tCIP + 6.77 ns in dual mode, R_FB = H). Channel deskew and skew tolerance up to 0.4×tCIP are handled automatically by the companion deserializer DS92LV3242.

Pinout & Package
DS92LV3241TVS/NOPB is housed in a 64-pin TQFP (PAG package) with exposed thermal pad. Pin functions are validated per TI SNLS314D datasheet Rev. April 2013.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TxIN[31:0] | Parallel LVCMOS data input | 32-bit wide synchronous data bus latched on TxCLKIN edge (rising/falling selectable via R_FB) |
| TxCLKIN | Parallel clock input | Strobe source for parallel data capture; determines maximum payload rate and mode boundaries |
| MODE | Mode select control | ACTIVE HIGH selects quad mode (40–85 MHz); LOW defaults to dual mode (20–50 MHz) |
| PDB | Power-down bar | ACTIVE LOW disables serializer, tri-states LVDS outputs, and shuts down PLL - reduces idle power to ≤50 µA |
| TxOUT[3:0]+/− | Differential LVDS serial output | Four pairs of high-speed embedded-clock outputs; support AC-coupled transmission up to 10 m over CAT-5 |
| R_FB | Rising/Falling edge select | Configures TxCLKIN edge used for data capture - critical for timing margin alignment with source logic |
| BISTEN | Built-in self-test enable | ACTIVE HIGH activates AT-speed BIST for end-to-end link validation without external pattern generators |
| VSEL / PRE | VOD & pre-emphasis control | VSEL sets differential swing (350–1000 mVP-P); PRE enables pre-emphasis for lossy channel compensation |
Key Features
| Feature | Design Value |
|---|---|
| Embedded clock architecture | Eliminates separate serial clock line and reference clock requirement - reduces PCB routing complexity and skew risk |
| Selectable dual/quad lane mode | Single MODE pin configures bandwidth and frequency range - enables one hardware design to serve VGA (dual) and HD (quad) applications |
| On-chip signal conditioning | DC-balance encoding + data randomization + transmit pre-emphasis ensures robust AC-coupled transmission over long cables |
| Integrated 100Ω LVDS termination | Reduces component count and board space; eliminates stub-induced reflections in point-to-point links |
| AT-speed BIST | Validates full SER/DES link integrity in-system using internal test patterns - no external equipment needed for production testing |
| Automatic plug-and-lock operation | Deserializer locks to random data without training sequences - simplifies startup and improves system reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS92LV3221TVS/NOPB | 24-bit serializer; lower max clock (66 MHz); no quad mode; smaller 48-pin TQFP | Suitable only for sub-HD resolutions (e.g., SXGA) and shorter reach (<5 m) | Select when bandwidth and pin count must be minimized and 32-bit width is unnecessary |
| MAX9249GTJ+T | GMSL-compatible serializer; 1.5 Gbps max; includes reverse-channel control and diagnostics | Designed for automotive camera links with bidirectional sideband communication | Choose for automotive ADAS systems requiring ASIL-B compliance and command/response feedback |
Compared with DS92LV3241TVS/NOPB, DS92LV3221TVS/NOPB offers reduced cost and footprint but sacrifices 32-bit width and quad-mode scalability, while MAX9249GTJ+T adds automotive-specific features at the expense of industrial temperature range and pure Channel Link II compatibility.

FAQ
What is the maximum supported data payload rate for DS92LV3241TVS/NOPB?
The DS92LV3241TVS/NOPB achieves a maximum data payload rate of 2.72 Gbps when operating in quad mode at 85 MHz (85 MHz × 32-bit). This is confirmed in the SNLS314D datasheet Section 1, "Features", and validated under Recommended Operating Conditions for f = 85 MHz, RANDOM pattern, MODE = H. The actual serial line rate exceeds this due to encoding overhead, but payload remains fixed at 2.72 Gbps.
How does DS92LV3241TVS/NOPB handle clock embedding and recovery?
DS92LV3241TVS/NOPB embeds the parallel clock (TxCLKIN) directly into the LVDS serial data stream using a self-synchronizing architecture. No separate serial clock line or external reference is required. The companion DS92LV3242 deserializes and recovers both clock and data via CDR/PLL circuitry - a capability explicitly stated in the Functional Description section of SNLS314D.
Can DS92LV3241TVS/NOPB operate with 1.8 V LVCMOS I/O levels?
Yes. DS92LV3241TVS/NOPB supports 1.8 V LVCMOS parallel I/O via the IOVDD pin, which accepts 1.71–1.89 V per the Recommended Operating Conditions table (page 7, SNLS314D). Input thresholds (VIH/VIL) and output drive strength are specified for both 1.8 V and 3.3 V configurations - enabling direct interfacing with low-voltage FPGAs and ASICs.
What is the purpose of the BISTEN pin on DS92LV3241TVS/NOPB?
The BISTEN pin on DS92LV3241TVS/NOPB enables Built-In Self-Test (BIST) mode when driven HIGH. In this mode, the serializer generates internal test patterns for end-to-end link validation with the DS92LV3242 deserializer - allowing system-level diagnostics without external pattern generators. BIST operation and error flag reporting are detailed in Section 8.4.3 of SNLS314D.
Does DS92LV3241TVS/NOPB require external LVDS termination resistors?
No. DS92LV3241TVS/NOPB integrates 100 Ω differential termination on all four TxOUT[3:0]± LVDS output pairs, as confirmed in the "Serializer LVDS DC Specifications" table (page 8, SNLS314D) and the "Features" list ("Integrated LVDS Terminations"). This eliminates the need for external resistors and minimizes stub length and board area.
