Texas Instruments DS92LV16TVHGX/NOPB

Overview

DS92LV16TVHGX/NOPB 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. It operates as a full-duplex transceiver or independent serializer/deserializer, enabling high-integrity data transmission across backplanes and cables in industrial instrumentation and video interconnect systems.

For engineers reviewing the DS92LV16TVHGX/NOPB datasheet, DS92LV16TVHGX/NOPB pinout, DS92LV16TVHGX/NOPB application, or DS92LV16TVHGX/NOPB equivalent, key selection criteria include its BLVDS signaling compliance, ±100 mV receiver input threshold, hot-plug synchronization capability, loss-of-lock reporting, and 80-pin LQFP package compatibility with PCB trace skew mitigation requirements.

Technical Context

The DS92LV16TVHGX/NOPB integrates independent transmit and receive blocks, each with dedicated PLLs: the serializer locks to TCLK (25–80 MHz), while the deserializer locks to REFCLK and recovers clock from the BLVDS stream. It supports line loopback (RIN→DO→ROUT) and local loopback (DIN→ROUT) for system-level diagnostics.

Its operation includes Initialization (PLL lock to local clocks), Data Transfer (16+2-bit framing with start/stop clock bits), Resynchronization (automatic lock recovery on loss), and Powerdown (μA-level current draw via TPWDN*/RPWDN*). The LOCK pin synchronously indicates valid ROUT[0:15] data, with deterministic jitter tolerance of ≤100 ps at 80 MHz.

Key Specifications

Pinout & Package

DS92LV16TVHGX/NOPB is housed in a compact, standard 80-pin LQFP package (12 mm × 12 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow TI's documented DS92LV16 pinout, supporting separate power domains (DVDD, PVDD, AVDD), independent enable/control signals (DEN, REN, TPWDN*, RPWDN*), and dedicated clock inputs (TCLK, REFCLK).

FAQ

What is the maximum supported clock rate for DS92LV16TVHGX/NOPB?

The DS92LV16TVHGX/NOPB supports a maximum clock rate of 80 MHz on both TCLK and REFCLK inputs. At this rate, it achieves a serial data rate of 1.44 Gbps (18×TCLK) and a payload throughput of 1.28 Gbps (16×TCLK), as confirmed in the SNLS138H datasheet Section 7.2 and Figure 19. Operation above 80 MHz is outside specification and may result in failed PLL lock or increased bit error rate.

Does DS92LV16TVHGX/NOPB require external PLL components?

No, DS92LV16TVHGX/NOPB integrates internal PLLs for both serializer and deserializer functions, eliminating the need for external loop filters, VCOs, or reference dividers. The serializer PLL locks directly to TCLK, and the deserializer PLL locks to the embedded clock in the BLVDS stream or to REFCLK during initialization, as specified in the Functional Description section of the datasheet.

How does the LOCK pin function on DS92LV16TVHGX/NOPB?

The LOCK pin on DS92LV16TVHGX/NOPB is an open-drain output that goes low when the deserializer PLL achieves and maintains lock to the incoming BLVDS stream. It remains low only while valid data appears on ROUT[0:15], and transitions high within 5 cycles upon loss of lock. This synchronous indicator allows real-time system monitoring without additional logic, as detailed in Sections 8.3 and 9.1 of SNLS138H.

Can DS92LV16TVHGX/NOPB operate with mismatched TCLK and REFCLK frequencies?

Yes, DS92LV16TVHGX/NOPB supports independent TCLK and REFCLK sources with a specified ratio tolerance of 0.95–1.05, allowing up to ±5% frequency mismatch. This enables use of locally generated clocks (e.g., crystal oscillators) on transmitter and receiver boards without requiring a shared clock source, as defined in the DESERIALIZER TIMING REQUIREMENTS table (tRFCP/tTCP ratio).

What package type and thermal characteristics does DS92LV16TVHGX/NOPB use?

DS92LV16TVHGX/NOPB uses an 80-pin LQFP package (12 mm × 12 mm, 0.5 mm pitch) with exposed thermal pad. Its thermal resistance is θJA = 43°C/W and θJC = 11.1°C/W, enabling operation up to +85°C ambient with standard 2-layer copper pour under the pad. Power dissipation is rated at 23.2 mW/°C above +25°C, per Absolute Maximum Ratings Table 1.
