Texas Instruments DS92LV3242TVS/NOPB

Overview

DS92LV3242TVS/NOPB from Texas Instruments is a 32-bit Channel Link II deserializer IC that recovers parallel LVCMOS data and clock from embedded-clock LVDS serial streams. It supports dual-lane (20–50 MHz) or quad-lane (40–85 MHz) operation, delivers up to 2.72 Gbps payload, and features automatic channel deskew, DC-balanced decoding, and >4 kV HBM ESD protection. It is used in industrial machine vision systems for high-reliability camera-to-processor video transport over CAT-5 cables.

For engineers reviewing the DS92LV3242TVS/NOPB datasheet, DS92LV3242TVS/NOPB pinout, DS92LV3242TVS/NOPB application, or DS92LV3242TVS/NOPB equivalent, key selection criteria include recovered clock jitter tolerance (0.25 UI), LVDS input skew tolerance (0.4 × tROCP), lock detection via LOCK pin, and support for AC-coupled interconnect with integrated 100 Ω termination.

Technical Context

The DS92LV3242TVS/NOPB implements a CDR/PLL-based receiver architecture that locks to random data without external reference clock or training patterns. It performs per-channel deskew of up to 0.4 × parallel clock period and aligns four LVDS input pairs (RxIN[3:0]±) to reconstruct a synchronous 32-bit LVCMOS output bus (RxOUT[31:0]) with recovered clock (RxCLKOUT).

Its signal conditioning includes built-in 100 Ω differential input termination, selectable RxCLKOUT edge polarity (via R_FB), and programmable output enable (REN). The device operates across −40°C to +85°C and supports both 1.8 V and 3.3 V LVCMOS I/O via IOVDD configuration - though DS92LV3242TVS/NOPB itself uses 3.3 V core and analog supplies (VDD = 3.3 V, VDDA = 3.3 V, VDDPLL = 3.3 V).

FAQ

What is the maximum supported cable length for DS92LV3242TVS/NOPB in quad-mode operation?

DS92LV3242TVS/NOPB supports up to 10 meters of CAT-5 cable at 2.72 Gbps (85 MHz quad-mode), as verified in TI's characterization using standard twisted-pair cabling and AC-coupled interconnect. Performance beyond 10 m depends on cable quality, connector losses, and pre-emphasis settings on the companion DS92LV3241 serializer.

Does DS92LV3242TVS/NOPB require an external reference clock to achieve lock?

No, DS92LV3242TVS/NOPB does not require an external reference clock. Its CDR/PLL architecture locks directly to the embedded clock within the incoming LVDS data stream - enabling true "plug-and-lock" operation without training patterns or sync characters, as confirmed in the SNLS314D functional description.

How does the LOCK pin behave during loss-of-signal events on DS92LV3242TVS/NOPB?

When DS92LV3242TVS/NOPB loses lock - e.g., due to interrupted LVDS input - the LOCK pin drives LOW, and RxOUT[31:0] and RxCLKOUT enter tri-state. Resynchronization initiates automatically on the master channel (RxIN0±); LOCK returns HIGH only after all channels relock and data alignment is restored.

Can DS92LV3242TVS/NOPB operate with 1.8 V LVCMOS I/O levels?

No - DS92LV3242TVS/NOPB itself does not accept 1.8 V I/O on its RxOUT pins. Its IOVDD supply is for the companion serializer (DS92LV3241); DS92LV3242TVS/NOPB uses 3.3 V for all digital and analog supplies (VDD, VDDA, VDDPLL), and its RxOUT[31:0] outputs swing rail-to-rail at 3.3 V LVCMOS levels.

What is the purpose of the R_FB pin on DS92LV3242TVS/NOPB?

The R_FB pin on DS92LV3242TVS/NOPB selects the edge polarity of the recovered RxCLKOUT signal: HIGH configures rising-edge clocking of RxOUT[31:0], LOW configures falling-edge clocking - allowing precise timing alignment with downstream capture logic such as FPGA input registers.
