Product details
Overview
SN65LVDS302ZQER from Texas Instruments is a programmable 27-bit SubLVDS serial-to-parallel receiver IC designed for high-speed video interface de-serialization in compact displays. It supports up to 24-bit RGB + 3 control bits over 1–3 SubLVDS differential pairs, delivers pixel clock frequencies from 4 MHz to 65 MHz, achieves up to 1.755 Gbps data throughput, and operates with 1.8-V supply at ≤27 μW standby power. It is used in mobile display interconnects between application processors and LCD drivers.
For engineers reviewing the SN65LVDS302ZQER datasheet, SN65LVDS302ZQER pinout, SN65LVDS302ZQER application, or SN65LVDS302ZQER equivalent, this page provides verified technical context, validated pin functions, confirmed operating modes (active/shutdown/standby), exact package mapping to nFBGA-80 (ZXH), and two documented alternative receivers for FlatLink™3G-compatible video links.
Technical Context
The SN65LVDS302ZQER implements a single 30-bit shift register that loads serial data from configurable SubLVDS lanes (1/2/3), validates parity, and latches 27 parallel CMOS outputs (R[7:0], G[7:0], B[7:0], HS, VS, DE, CPE). Its PLL locks to incoming SubLVDS pixel clocks (CLK±) across 4–65 MHz and generates a clean PCLK output with selectable edge polarity via CPOL.
It features three distinct power states: active mode (e.g., 17 mW at QVGA), shutdown (<1 μW), and standby (27 μW), controlled by RXEN and automatic clock-detection logic. The bus-swap function (SWAP pin) reorders R/G/B output pin assignments to simplify PCB layout without signal routing changes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial-to-parallel video receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS301ZQER | Transmitter (not receiver); complementary companion chip in FlatLink™3G link | Used on source side (SoC/processor); requires SN65LVDS302ZQER on sink side | Select SN65LVDS301ZQER only when building full transmitter-receiver pair; not a functional substitute |
| SN65LVDS314RTVR | 8-bit SubLVDS receiver; no parity checking; no bus-swap; 48-pin WQFN | Suitable for simpler monochrome or low-resolution interfaces; lacks 27-bit RGB support and error handling | Choose SN65LVDS314RTVR only for cost-sensitive, low-data-rate applications where full RGB+control and robustness are unnecessary |
Compared with SN65LVDS301ZQER (transmitter) and SN65LVDS314RTVR (8-bit receiver), SN65LVDS302ZQER uniquely delivers 27-bit programmable SubLVDS reception with parity validation, bus-swap, and multi-mode power control - making it irreplaceable for high-fidelity mobile RGB display links requiring reliability and layout flexibility.

FAQ
What is the primary function of the SN65LVDS302ZQER in a display system?
The SN65LVDS302ZQER functions as a programmable 27-bit SubLVDS serial-to-parallel receiver that de-serializes incoming video data from 1–3 differential lanes into a parallel 24-bit RGB + 3 control bit CMOS bus. It recovers pixel clock, validates parity, and drives timing signals (PCLK, HS, VS, DE) for LCD drivers. Its role is essential for bridging high-speed serial video links to parallel display interfaces in mobile devices.
How does the SN65LVDS302ZQER handle data integrity errors?
The SN65LVDS302ZQER performs real-time parity checking on each 30-bit received word. When a parity error is detected, the Channel Parity Error (CPE) output asserts a high pulse for half a PCLK cycle, and the device holds the previous valid pixel data on all R/G/B outputs for one additional clock cycle. This prevents corrupted pixels from appearing on-screen and allows system-level error logging via CPE monitoring.
What power-saving modes does the SN65LVDS302ZQER support, and how are they activated?
The SN65LVDS302ZQER supports three power modes: active (enabled via RXEN = high), shutdown (RXEN = low, 0.7 μW), and auto-standby (triggered when PCLK falls below 500 kHz, 27 μW). Shutdown requires ≥10 µs low pulse on RXEN; standby activates automatically without software intervention. These modes enable aggressive power gating in battery-operated devices like smartphones and wearables.
Can the SN65LVDS302ZQER be used with different numbers of SubLVDS data lanes?
Yes - the SN65LVDS302ZQER supports 1-, 2-, or 3-lane SubLVDS operation, selected dynamically via LS0 and LS1 control inputs. Each configuration maps to specific PLL bandwidths and maximum pixel clock frequencies (e.g., 3-lane supports up to 65 MHz for XGA). Unused lanes (D1±, D2±) enter high-impedance state, simplifying layout and enabling one hardware design across multiple display resolutions.
What is the purpose of the SWAP pin on the SN65LVDS302ZQER?
The SWAP pin on the SN65LVDS302ZQER controls the physical ordering of the R[7:0], G[7:0], and B[7:0] output pins. When SWAP = low, outputs follow R7→R0, G7→G0, B7→B0 order; when SWAP = high, the order reverses to B0→B7, G0→G7, R0→R7. This feature allows identical PCB footprints for top- or bottom-side placement of the IC, eliminating layer swaps and reducing routing complexity in tight mobile layouts.
