Texas Instruments SN65LVDS86AQDGGR

Overview

SN65LVDS86AQDGGR from Texas Instruments is an automotive-grade LVDS receiver IC that converts 4-channel high-speed differential data (A0P/A0M, A1P/A1M, A2P/A2M, CLKINP/CLKINM) into 21-bit LVTTL parallel output (D0–D20 + CLKOUT) for flat-panel display interfaces. It operates from a single 3.3-V supply, supports 31–68 MHz input clock frequencies, delivers up to 178.5 MB/s throughput, and is qualified for −40°C to 125°C operation.

For engineers reviewing the SN65LVDS86AQDGGR datasheet, SN65LVDS86AQDGGR pinout, SN65LVDS86AQDGGR application, or SN65LVDS86AQDGGR equivalent, key selection criteria include its automotive temperature rating, 21-bit LVTTL output mapping, LVDS input compliance with ANSI EIA/TIA-644, integrated PLL with no external components, and shutdown control via active-low SHTDN.

Technical Context

The SN65LVDS86AQDGGR implements three 7-bit serial-in/parallel-out shift registers synchronized to a recovered LVDS clock, enabling 7× oversampling of incoming data before parallel output at CLKIN rate. Its internal PLL locks to differential clock inputs without external loop filters or capacitors, supporting wide-frequency acquisition (31–68 MHz) and tolerating up to 50 ps input jitter.

Input termination uses four 100-Ω resistors across the three data pairs and one clock pair; outputs drive standard LVTTL loads with VOH ≥ 2.4 V (IOH = −4 mA) and VOL ≤ 0.4 V (IOL = 4 mA). The SHTDN pin enables full functional disable, reducing ICC to 280 µA while clearing all internal registers to logic low.

FAQ

What is the primary function of the SN65LVDS86AQDGGR in a display system?

The SN65LVDS86AQDGGR functions as an LVDS-to-LVTTL deserializer, receiving four differential LVDS signals (three data pairs and one clock pair) and converting them into a 21-bit parallel LVTTL output bus (D0–D20 + CLKOUT). It enables high-speed, low-EMI transmission of RGB pixel data from graphics controllers to display drivers in automotive and industrial applications. This core function is implemented in the SN65LVDS86AQDGGR using integrated shift registers and a jitter-tolerant PLL.

Does the SN65LVDS86AQDGGR require external passive components for PLL operation?

No, the SN65LVDS86AQDGGR does not require any external passive components for PLL operation. Its internal PLL is fully self-contained and achieves lock across the 31–68 MHz input clock range without external loop filters, capacitors, or resistors. This simplifies design, reduces bill-of-materials cost, and improves layout reliability-key advantages confirmed in the SLLS318D datasheet section "No External Components Required for PLL." The SN65LVDS86AQDGGR maintains this behavior across its full automotive temperature range.

How does the SHTDN pin affect the internal state of the SN65LVDS86AQDGGR?

When the SHTDN pin is driven low, the SN65LVDS86AQDGGR inhibits the internal clock, shuts off the LVDS receivers, and clears all internal shift registers to logic low. This results in zero valid data on D0–D20 outputs and places CLKOUT in a high-impedance or inactive state. Power consumption drops to 280 µA, making it suitable for dynamic power management. The SN65LVDS86AQDGGR resumes normal operation within 1 ms after SHTDN is released, as specified in the "Enable time" parameter (ten = 1 ms).

What is the significance of the 4-kV HBM ESD rating for the SN65LVDS86AQDGGR?

The 4-kV Human Body Model (HBM) ESD rating for the SN65LVDS86AQDGGR reflects its robustness against electrostatic discharge during handling and assembly in automotive manufacturing environments. This rating exceeds standard industrial requirements and aligns with AEC-Q100 stress test protocols, ensuring reliability in high-volume production lines where static charge buildup is common. The SN65LVDS86AQDGGR achieves this through on-chip protection structures on all pins, validated per MIL-STD-883C Method 3015.7.

Can the SN65LVDS86AQDGGR be used with non-TI LVDS transmitters?

Yes, the SN65LVDS86AQDGGR can be used with non-TI LVDS transmitters provided they comply with the ANSI EIA/TIA-644 standard for electrical characteristics-including differential voltage swing (0.1–0.6 V), common-mode range (0.0–2.4 V), and impedance matching. The SN65LVDS86AQDGGR's input thresholds (±100 mV) and termination requirements (100-Ω across each differential pair) are standardized, enabling interoperability with compatible third-party transmitters in display interface applications.
