Texas Instruments DS92LV16TVHG

Overview

DS92LV16TVHG from Texas Instruments is a monolithic 16-bit parallel-to-serial/serial-to-parallel Bus LVDS SERDES IC supporting 25–80 MHz clock rates, delivering 2.56 Gbps full-duplex throughput with embedded clock recovery, ±100 mV receiver input threshold, and operation across −40°C to +85°C for backplane and cable interconnects in industrial imaging systems.

For engineers reviewing the DS92LV16TVHG datasheet, DS92LV16TVHG pinout, DS92LV16TVHG application, or DS92LV16TVHG equivalent, this page delivers verified SERDES timing parameters, BLVDS interface behavior, hot-plug synchronization logic, loss-of-lock reporting, and LQFP-80 package implementation guidance - all confirmed from TI's SNLS138H revision April 2013 official documentation.

Technical Context

The DS92LV16TVHG integrates independent serializer and deserializer blocks sharing a single die, each with dedicated PLLs: the serializer locks to TCLK (25–80 MHz), while the deserializer locks to REFCLK (same frequency range) or recovers clock from the incoming BLVDS stream. Both blocks support initialization, data transfer, resynchronization, powerdown, and TRI-STATE states.

It implements 16:1 serialization with two embedded clock bits (start/stop), yielding 18-bit frames at 18×TCLK rate; payload remains 16×TCLK. The deserializer provides RCLK synchronous to ROUT[0:15], with LOCK pin indicating valid output data, and supports line loopback (RIN→DO→ROUT) and local loopback (DIN→ROUT) for system-level diagnostics.

FAQ

What clock frequencies does the DS92LV16TVHG support?

The DS92LV16TVHG supports a transmit clock (TCLK) and reference clock (REFCLK) range of 25 MHz to 80 MHz, with ±5% frequency tolerance. At 80 MHz, it achieves 1.28 Gbps payload throughput (16×TCLK) and 1.44 Gbps serial line rate (18×TCLK). The device's PLL architecture ensures stable lock across this full range without external components, as confirmed in TI's SNLS138H datasheet Section 7.3.

Does the DS92LV16TVHG require external encoding or clock forwarding?

No, the DS92LV16TVHG embeds clock information directly into the serial stream using start and stop bits - eliminating the need for 8b/10b or other encoding schemes. This reduces latency, avoids bandwidth overhead, and simplifies FPGA interface logic. The deserializer recovers both clock and data from the same BLVDS pair, as detailed in Functional Description section of the DS92LV16TVHG datasheet.

How does the DS92LV16TVHG handle loss of synchronization?

When the DS92LV16TVHG deserializer loses lock - detected after two consecutive invalid clock edges - it drives the LOCK pin high and places ROUT[0:15] and RCLK into TRI-STATE. It then automatically attempts resynchronization to random data or responds to a SYNC pulse from the serializer. Recovery time varies: sync-pattern lock takes ≤513×tTCP (~6.4 µs at 80 MHz), while random lock is data-dependent and unspecified.

What is the meaning of the LOCK pin behavior in DS92LV16TVHG?

The LOCK pin on the DS92LV16TVHG is an open-drain CMOS output that goes low only when the deserializer's PLL has achieved stable lock to the incoming BLVDS stream and ROUT[0:15] data is valid and synchronous to RCLK. It remains high during power-up, initialization, resynchronization, or loss-of-lock events. This provides hardware-level, zero-latency fault signaling for system monitoring without software intervention.

Can the DS92LV16TVHG operate with independent transmit and receive clocks?

Yes, the DS92LV16TVHG supports independent TCLK (for serializer) and REFCLK (for deserializer) inputs, each ranging from 25 MHz to 80 MHz. They must be within ±5% frequency match for reliable initialization, but may originate from separate oscillators - enabling asynchronous domain bridging in multi-FPGA systems. This capability is explicitly documented in the "Independent Transmitter and Receiver Operation" feature and timing tables of the DS92LV16TVHG datasheet.
