Texas Instruments SN65LVDS302ZQE

Overview

SN65LVDS302ZQE from Texas Instruments is a programmable 27-bit SubLVDS serial-to-parallel receiver used to deserialize high-speed video data for LCD interface applications. It supports up to 24-bit RGB + 3 control bits over 1–3 SubLVDS differential lanes, delivers up to 1.755-Gbps throughput, operates with pixel clock range of 4–65 MHz, and features bus-swap functionality for PCB layout flexibility.

For engineers reviewing the SN65LVDS302ZQE datasheet, SN65LVDS302ZQE pinout, SN65LVDS302ZQE application, or SN65LVDS302ZQE equivalent, this page provides verified technical context, real-world timing behavior, power mode trade-offs, CMOS output drive capability, and validated alternative options for mobile display interface design.

Technical Context

The SN65LVDS302ZQE implements a configurable PLL-based deserialization architecture that locks to incoming SubLVDS pixel clocks (4–65 MHz) and reconstructs parallel 27-bit outputs (R[7:0], G[7:0], B[7:0], HS, VS, DE, CPE). Its three operating modes-active, standby, and shutdown-enable dynamic power scaling: 17 mW at QVGA active mode, 27 μW in standby, and 0.7 μW in shutdown.

It performs real-time parity checking on received serial data; upon error detection, it asserts a half-cycle-high CPE pulse and holds the previous valid pixel word on outputs. Input skew margin (tRSKM) is mode-dependent: 630 ps (1/2-channel), 360 ps (3-channel), directly tied to PLL bandwidth (0.087×fPCLK or 0.075×fPCLK) and interconnect jitter budgeting.

FAQ

What is the maximum pixel clock frequency supported by the SN65LVDS302ZQE?

The SN65LVDS302ZQE supports pixel clock frequencies up to 65 MHz in 3-channel receive mode, enabling XGA resolution displays. In 2-channel mode, max is 30 MHz (VGA), and in 1-channel mode, max is 15 MHz (QVGA). These limits are defined by PLL bandwidth and input skew margin constraints per datasheet Section 6.3.

How does the SN65LVDS302ZQE handle data corruption during serial transmission?

The SN65LVDS302ZQE performs real-time parity checking on each received 30-bit word. If a parity error is detected, it asserts the CPE output with a high pulse lasting half a PCLK cycle and holds the previous valid pixel word on all R/G/B outputs for one additional clock cycle - preventing corrupted data from propagating to the display.

Can the SN65LVDS302ZQE be used with only one SubLVDS data lane?

Yes, the SN65LVDS302ZQE supports 1-, 2-, or 3-lane SubLVDS operation via LS0 and LS1 pin configuration. In 1-lane mode, it receives all 27 bits (24 RGB + 3 control) sequentially over D0+/D0–, achieving up to 15 MHz pixel clock and 1.755-Gbps aggregate throughput.

What is the purpose of the SWAP pin on the SN65LVDS302ZQE?

The SWAP pin on the SN65LVDS302ZQE reverses the order of parallel output pins: when SWAP = low, R7–R0/G7–G0/B7–B0 appear left-to-right; when SWAP = high, B0–B7/G0–G7/R0–R7 appear left-to-right. This allows identical PCB layouts for top- or bottom-side placement without redesign.

Does the SN65LVDS302ZQE require external termination resistors on SubLVDS inputs?

No - the SN65LVDS302ZQE integrates internal 78–122 Ω differential termination resistors on all SubLVDS inputs (CLK±, D0±, D1±, D2±), eliminating need for external resistors and reducing BOM count and board area in space-constrained mobile designs.
