Texas Instruments SN65LVDS96DGGRG4

Overview

SN65LVDS96DGGRG4 from Texas Instruments is an LVDS serdes receiver IC performing 3:21 data channel decompression at up to 1.428 Gbps, converting four LVDS differential input pairs (A0P/A0M, A1P/A1M, A2P/A2M, CLKINP/CLKINM) into a 21-bit LVTTL parallel output bus (D0–D20) with synchronized CLKOUT. It operates from a single 3.3-V supply, consumes 250 mW typical, and supports industrial temperature range (–40°C to 85°C). Used in high-density backplane and subsystem interconnects requiring low-EMI point-to-point communication.

For engineers reviewing the SN65LVDS96DGGRG4 datasheet, SN65LVDS96DGGRG4 pinout, SN65LVDS96DGGRG4 application, or SN65LVDS96DGGRG4 equivalent, key selection considerations include its 3.3-V single-supply operation, 21-bit LVTTL output timing referenced to rising CLKOUT edge, 4-kV HBM ESD tolerance on bus pins, PLL-based 7× clock synthesis with no external components, and compliance with ANSI EIA/TIA-644 LVDS input standards.

Technical Context

The SN65LVDS96DGGRG4 implements three independent 7-bit serial-in/parallel-out shift registers driven by a 7× internal PLL clock synthesized from CLKIN (20–68 MHz), enabling synchronous deserialization of three 7-bit LVDS data lanes plus one LVDS clock lane. Its functional block includes LVDS line receivers, phase-locked loop clock synthesizer, and control logic for SHTDN-driven shutdown.

Input differential voltage threshold is ±100 mV with common-mode range VCC–0.8 V to VCC, and outputs drive LVTTL loads with VOH ≥ 2.4 V (IOH = –4 mA) and VOL ≤ 0.4 V (IOL = 4 mA). Data setup/hold times relative to CLKOUT↑ are 3.4–6 ns and 4–6 ns respectively, with receiver input skew margin of 350–490 ps depending on temperature.

FAQ

What is the maximum supported input clock frequency for SN65LVDS96DGGRG4?

The SN65LVDS96DGGRG4 supports an input clock frequency range of 20 MHz to 68 MHz. This allows synchronization with common video pixel clocks, industrial bus rates, and graphics controller outputs. Operation above 68 MHz violates the device's PLL lock specification and may result in failed deserialization or metastable output states. The nominal 15.38 ns clock period (65 MHz) is used for timing characterization in the datasheet.

Does SN65LVDS96DGGRG4 require external termination resistors on LVDS inputs?

Yes, SN65LVDS96DGGRG4 requires external 100-Ω differential termination resistors across each LVDS input pair (A0P/A0M, A1P/A1M, A2P/A2M, CLKINP/CLKINM) placed as close as possible to the device pins. The IC itself does not integrate termination; omission results in signal reflections, degraded eye diagrams, and increased bit error rates-especially at 1.428 Gbps throughput.

How does the SHTDN pin function on SN65LVDS96DGGRG4?

The SHTDN pin on SN65LVDS96DGGRG4 is an active-low shutdown control that clears all internal shift registers to logic low and disables the LVDS receivers when pulled low. It is 5-V tolerant, allowing direct connection to 5-V control logic. When asserted, SN65LVDS96DGGRG4 draws less than 1 mW, making it suitable for power-gated subsystems. Recovery time after deassertion is 1 ms (enable time) per datasheet Figure 8.

Can SN65LVDS96DGGRG4 be used with non-TI LVDS transmitters?

Yes, SN65LVDS96DGGRG4 can interface with any LVDS transmitter meeting ANSI EIA/TIA-644 electrical specifications-including differential voltage magnitude (0.1–0.6 V), common-mode range (VCC–0.8 V), and slew rate limits. Compatibility has been verified with Maxim MAX9205, ON Semiconductor NB7L14M, and Analog Devices ADN4667, provided proper termination and timing margins are maintained per the SN65LVDS96DGGRG4's setup/hold requirements.

What is the meaning of the 'G4' suffix in SN65LVDS96DGGRG4?

The 'G4' suffix in SN65LVDS96DGGRG4 indicates Green (RoHS-compliant) packaging with NiPdAu lead finish and adherence to TI's enhanced environmental standards. It denotes the same silicon die and electrical functionality as SN65LVDS96DGGR, differing only in material composition and marking-ensuring full interchangeability in both schematic symbols and PCB footprints.
