Product details
Overview
SN65LVDS86AQDGGG4 from Texas Instruments is an automotive-grade LVDS deserializer IC that converts 4-channel LVDS serial 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 frequency, delivers up to 178.5 MB/s throughput, and is qualified for −40°C to 125°C operation.
For engineers reviewing the SN65LVDS86AQDGGG4 datasheet, SN65LVDS86AQDGGG4 pinout, SN65LVDS86AQDGGG4 application, or SN65LVDS86AQDGGG4 equivalent, key selection criteria include its 48-pin TSSOP package, 21-bit LVTTL output timing referenced to falling CLKOUT edge, shutdown control via active-low SHTDN, and compatibility with SVGA/XGA/SXGA display controllers in automotive infotainment and ADAS displays.
Technical Context
The SN65LVDS86AQDGGG4 implements three 7-bit serial-in/parallel-out shift registers synchronized to a PLL-locked input clock, enabling 3:21 data channel expansion. Its LVDS receivers comply with ANSI EIA/TIA-644, support differential input voltage range of ±100 mV threshold, and require only four external 100-Ω termination resistors.
Internal clock generation eliminates need for external crystals or oscillators; phase-lock acquisition occurs within 1 ms of SHTDN deassertion. Output timing guarantees setup/hold of 5 ns relative to CLKOUT↓, with receiver input skew margin of 550–700 ps at 65 MHz, supporting robust timing in high-noise automotive cable runs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–3.6 V - Single-rail operation compatible with standard 3.3-V system rails; no level-shifting required. |
| Input Clock Range | 31–68 MHz - Supports SVGA (31.5 MHz), XGA (65 MHz), and SXGA (79.9 MHz) pixel clocks via PLL multiplication. |
| Data Throughput | 178.5 MB/s - Achieved by 7× oversampling of LVDS data stream, enabling 21-bit parallel output at base clock rate. |
| ESD Rating | ±4 kV HBM - Meets automotive board-level ESD immunity requirements per ISO 10605. |
| Operating Temperature | −40°C to +125°C - Qualified per AEC-Q100 Grade 1; suitable for under-hood and dashboard display modules. |
| Quiescent Current | 43 mA typical at 65 MHz - Enables low-power display interface without sacrificing timing performance. |
| Output Timing Edge | Falling edge of CLKOUT - Data D0–D20 valid on CLKOUT↓, simplifying synchronous capture in FPGA or ASIC logic. |
Pinout & Package
Packaged in 48-pin Thin Shrink Small-Outline Package (TSSOP, DGG), 12.6 mm × 6.1 mm × 1.2 mm max height, 0.5-mm pitch, RoHS-compliant NiPdAu lead finish, MSL Level-2-260°C-1 year.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0P / A0M | LVDS Data Channel 0 Differential Pair | Receives first 7-bit serialized data lane; requires 100-Ω differential termination at receiver end. |
| A1P / A1M | LVDS Data Channel 1 Differential Pair | Receives second 7-bit serialized data lane; electrically isolated from A0 and A2 for skew control. |
| A2P / A2M | LVDS Data Channel 2 Differential Pair | Receives third 7-bit serialized data lane; enables full 21-bit RGB+sync mapping (e.g., R[5:0], G[5:0], B[5:0], H/VSYNC). |
| CLKINP / CLKINM | LVDS Clock Differential Pair | Synchronizes internal PLL and shift registers; jitter tolerance ≤50 ps ensures stable lock across temperature. |
| D0–D20 | LVTTL Parallel Output Bus | 21-bit single-ended outputs driven at 3.3-V LVTTL levels; D0–D17 map to RGB data, D18–D20 to sync/control signals. |
| CLKOUT | LVTTL Output Clock | Falling-edge-aligned clock for latching D0–D20; derived from PLL output, not buffered input clock. |
| SHTDN | Active-Low Shutdown Control | Pulls all internal registers low and disables LVDS receivers; reduces ICC to 280 µA when asserted. |
| LVDSVCC / PLLVCC / VCC | Power Rails | Three independent 3.3-V supplies: LVDSVCC powers receivers, PLLVCC powers PLL core, VCC powers LVTTL outputs. |
| LVDSGND / PLLGND / GND | Ground Planes | Separate ground returns minimize noise coupling between high-speed LVDS inputs, PLL, and digital outputs. |
Key Features
| Feature | Design Value |
|---|---|
| No external PLL components | Integrated PLL eliminates crystal, capacitors, and loop filter - reduces BOM count and layout area by ≥4 parts. |
| Low EMI LVDS interface | Differential signaling with <100 mV common-mode noise rejection suppresses radiated emissions in display cables. |
| Automotive temperature qualification | −40°C to +125°C operation validated per AEC-Q100; supports display modules in engine bay or sun-exposed dashboards. |
| Transparent data transmission | Bit-for-bit reconstruction from transmitter (e.g., SN75LVDS84/85); no protocol translation or frame buffering required. |
| Low-power shutdown mode | 280 µA quiescent current during SHTDN assertion - enables rapid power cycling in head-unit sleep/wake sequences. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS86A-Q1 | Identical electrical specs and pinout; automotive qualification includes AEC-Q100 Grade 0 (−40°C to +150°C) and enhanced HTOL testing. | Required for safety-critical HUD or ADAS displays where junction temperature exceeds 125°C. | Select SN65LVDS86A-Q1 when operating ambient exceeds 125°C or functional safety certification (ISO 26262) is mandated. |
| SN75LVDS86ADGG | Commercial-grade variant; same architecture but rated for 0°C to +70°C only; identical 48-pin TSSOP package and pinout. | Suitable for non-automotive industrial panels or lab prototypes where extended temperature is not required. | Choose SN75LVDS86ADGG for cost-sensitive non-automotive designs with controlled thermal environments. |
Compared with SN65LVDS86AQDGGG4, the SN65LVDS86A-Q1 extends junction temperature capability for extreme under-hood use, while SN75LVDS86ADGG trades automotive qualification for lower unit cost in benign environments - both retain identical timing, pinout, and functional behavior.

FAQ
What is the primary function of the SN65LVDS86AQDGGG4 in a display interface?
The SN65LVDS86AQDGGG4 functions as a 4-channel LVDS-to-21-bit LVTTL deserializer. It receives serialized pixel and sync data over three differential data pairs (A0, A1, A2) and one differential clock pair (CLKIN), then reconstructs them into a parallel 21-bit LVTTL bus (D0–D20 + CLKOUT) for direct connection to LCD timing controllers. This enables high-bandwidth, low-EMI video transport in automotive displays.
Does the SN65LVDS86AQDGGG4 require external passive components for basic operation?
Yes - the SN65LVDS86AQDGGG4 requires four 100-Ω differential termination resistors: one each across A0P/A0M, A1P/A1M, A2P/A2M, and CLKINP/CLKINM. No external crystal, capacitors, or loop filter components are needed, as the PLL is fully integrated. Power supply decoupling (0.1 µF ceramic per VCC pin) is also mandatory per layout guidelines.
How does the SN65LVDS86AQDGGG4 handle power-down and wake-up sequencing?
The SN65LVDS86AQDGGG4 uses an active-low SHTDN pin: asserting SHTDN pulls all internal registers low and disables LVDS receivers, reducing quiescent current to 280 µA. Release of SHTDN initiates PLL lock within 1 ms (ten), after which valid data appears on D0–D20 aligned to CLKOUT↓. No external reset sequencing is required.
Is the SN65LVDS86AQDGGG4 pin-compatible with the commercial SN75LVDS86A series?
Yes - the SN65LVDS86AQDGGG4 shares identical 48-pin TSSOP (DGG) package dimensions, pinout, and electrical interface with SN75LVDS86ADGG and SN75LVDS86ADGGR. The only differences are temperature rating (−40°C to +125°C vs. 0°C to +70°C) and automotive qualification; PCB layout and firmware can be reused across both variants.
What display resolutions does the SN65LVDS86AQDGGG4 support, and how is bandwidth calculated?
The SN65LVDS86AQDGGG4 supports SVGA (800×600), XGA (1024×768), and SXGA (1280×1024) resolutions. Bandwidth is calculated as 7× input clock rate × number of LVDS lanes: at 65 MHz input clock, 3 data lanes × 7 bits × 65 MHz = 1365 Mbps = 170.6 MB/s; peak throughput reaches 178.5 MB/s at 68 MHz, sufficient for 1280×720@60 Hz with blanking.
