Product details

Overview

SN65LVDS301ZXH from Texas Instruments is a programmable 27-bit parallel-to-serial transmitter implementing FlatLink™3G SubLVDS technology. It converts 24-bit RGB video, 3 control bits, 1 parity bit, and 2 reserved bits into 1–3 differential serial streams at up to 1755 Mbps, operating from a 1.8-V supply with pixel clock support from 4 MHz to 65 MHz. It serves as the interface between application processors and high-resolution displays in space-constrained portable electronics.

For engineers reviewing the SN65LVDS301ZXH datasheet, SN65LVDS301ZXH pinout, SN65LVDS301ZXH application, or SN65LVDS301ZXH equivalent, key selection criteria include SubLVDS output compliance, 3-mode link configuration (1/2/3-channel), failsafe CMOS inputs, bus-swap capability for PCB layout flexibility, and SAE J1752/3 'M'-spec EMI performance.

Technical Context

The SN65LVDS301ZXH integrates a programmable PLL with bandwidth scaling per pixel clock frequency (e.g., 7.0% of f_PCLK at 65 MHz) and supports three distinct transmit modes-active QVGA (17.4 mW typ), active VGA (28.8 mW typ), shutdown (0.5 μA typ), and standby (0.5 μA typ). Its internal 30-bit shift register latches data on PCLK edges (rising/falling selectable via CPOL) and appends odd-parity for error detection.

It features dedicated analog/digital/IO supply domains (VDDPLLA, VDDPLLD, VDDLVDS), independent ground planes (GNDPLLA, GNDPLLD, GNDLVDS), and glitch-suppressed TXEN enabling/disabling with ≥10 μs pulse width requirement. Output timing uncertainty (t_PPosx) is specified across all modes with jitter budgets traceable to SN65LVDS302 receiver compatibility.

Equivalent & Alternatives

The following parts are listed as comparable options for similar parallel-to-serial video interface applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN65LVDS311ZXH	Same 80-pin nFBGA package, but supports 36-bit input (30 data + 6 control) and higher max PCLK (85 MHz); no bus swap or SWAP pin	Better suited for WUXGA or dual-channel timing controllers; lacks layout flexibility for constrained PCBs	Choose SN65LVDS311ZXH only if >27-bit data width or >65 MHz PCLK is required; otherwise SN65LVDS301ZXH offers superior layout adaptability
SN65LVDS302PWP	Complementary receiver (not transmitter); 80-pin TSSOP package; designed specifically for SN65LVDS301ZXH output format and timing	Used exclusively on display side to deserialize SubLVDS stream back to parallel RGB; not functionally substitutable	SN65LVDS302PWP is the intended receiver partner - not a drop-in alternative, but the only device guaranteed to meet t_PPosx-based jitter budget alignment

Compared with SN65LVDS311ZXH and SN65LVDS302PWP, the SN65LVDS301ZXH uniquely balances 27-bit video serialization, bus-swap layout flexibility, and ultra-low EMI for portable displays - whereas SN65LVDS311ZXH trades configurability for bandwidth, and SN65LVDS302PWP serves only as its matched receiver.

FAQ

What is the maximum pixel clock frequency supported by the SN65LVDS301ZXH in 3-channel mode?

The SN65LVDS301ZXH supports a maximum pixel clock frequency of 65 MHz in 3-channel mode, enabling transmission of XGA (1024×768) video with effective throughput up to 1755 Mbps. This is confirmed in Section 6.3 Recommended Operating Conditions and Figure 6-6 PLL Bandwidth characterization.

Does the SN65LVDS301ZXH require external termination resistors for SubLVDS outputs?

No, the SN65LVDS301ZXH does not require external termination resistors for SubLVDS outputs. Its differential outputs are internally terminated to 100 Ω (per Figure 7-3 test circuit), and the datasheet specifies Z_OD(CLK) = 210 Ω small-signal output impedance - matching standard SubLVDS receiver input requirements without added components.

How does the bus swap (SWAP) feature affect the SN65LVDS301ZXH pin assignment for RGB data inputs?

When SWAP = 0, RGB data inputs follow standard ordering: R0–R7 on pins A5/C2 through B9/G2, G0–G7 on B1/B5 through B5/B1, and B0–B7 on B9/G2 through A5/C2. When SWAP = 1, the order is reversed - R7–R0, G7–G0, B7–B0 - allowing identical PCB footprints for top/bottom board placement without redesigning routing layers.

Can the SN65LVDS301ZXH operate with a pixel clock below 4 MHz?

Yes, the SN65LVDS301ZXH can accept pixel clock inputs as low as 1 Hz, but frequencies below 500 kHz force the device into standby mode, and frequencies between 500 kHz and 3 MHz may not reliably activate the transmitter. For guaranteed active-mode operation, PCLK must exceed 3 MHz - verified in Section 6.3 and Figure 7-9.

What is the purpose of the separate VDDPLLA, VDDPLLD, and VDDLVDS supplies on the SN65LVDS301ZXH?

The SN65LVDS301ZXH uses separate supplies - VDDPLLA (PLL analog), VDDPLLD (PLL digital), and VDDLVDS (SubLVDS I/O) - to isolate noise-sensitive circuits. This prevents digital switching noise from degrading PLL phase noise (Figure 6-18) and ensures clean SubLVDS output swing (Figure 6-5), directly supporting SAE J1752/3 'M'-spec EMI compliance.
