Product details
Overview
SN65LVDS301ZQE 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 high-speed interface between application processors and display modules in compact portable displays.
For engineers reviewing the SN65LVDS301ZQE datasheet, SN65LVDS301ZQE pinout, SN65LVDS301ZQE application, or SN65LVDS301ZQE 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 SN65LVDS301ZQE integrates a programmable PLL with bandwidth scaling (7.0–8.5% of PCLK), a 30-bit shift register loaded per pixel clock edge, and independent SubLVDS drivers for D0/D1/D2 and CLK outputs. Its three operating modes-active (QVGA/VGA), standby, and shutdown-are controlled via TXEN and pixel clock presence, enabling dynamic power management down to 0.5 μA.
It supports configurable data mapping via SWAP and LS0/LS1 pins, delivers odd-parity error detection on the 30-bit word, and maintains failsafe input protection across all CMOS inputs (VIH/VIL thresholds defined relative to VDD). Output common-mode voltage is tightly regulated at 0.9 V ±0.1 V with differential swing of 100–200 mV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65–1.95 V; enables low-power operation compatible with modern mobile SoCs and reduces system-level power delivery complexity. |
| Pixel Clock Range | 4–65 MHz; supports QVGA (4–15 MHz), VGA (8–30 MHz), and XGA+ (20–65 MHz) display resolutions across 1/2/3-channel modes. |
| Data Throughput | Up to 1755 Mbps (3-channel @ 65 MHz); achieves >20 dB EMI reduction vs parallel RGB interfaces, meeting automotive-grade SAE J1752/3 'M'-spec. |
| Power Consumption | 17.4 mW (QVGA active), 28.8 mW (VGA active), 0.5 μA (shutdown); enables battery-sensitive wearable and mobile applications. |
| Output Interface | SubLVDS differential signaling (D0+/−, D1+/−, D2+/−, CLK+/−); provides robust noise immunity and reduced crosstalk over FPC cables. |
| Input Protection | Failsafe CMOS inputs tolerate up to 2.165 V while VDD is 0–1.65 V; prevents latch-up and current injection during power sequencing. |
| ESD Rating | >2 kV HBM; ensures reliability during handling and assembly in high-volume portable electronics manufacturing. |
Pinout & Package
SN65LVDS301ZQE is packaged in an 80-ball nFBGA (ZXH) with 0.5-mm pitch and nominal body size 5.00 mm × 5.00 mm. The package supports fine-pitch routing for space-constrained display interface designs and thermal performance characterized by RθJA = 47.6 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0+, D0− | SubLVDS Data Link 0 | Always active differential output pair; carries first segment of serialized 30-bit word in all link configurations. |
| D1+, D1− | SubLVDS Data Link 1 | Active only when LS0≠LS1; enables 2-channel mode (15-bit segments) or 3-channel mode (10-bit segments). |
| D2+, D2− | SubLVDS Data Link 2 | Active only when LS0=low & LS1=high; enables full 3-channel mode with 10-bit segmentation per link. |
| CLK+, CLK− | SubLVDS Pixel Clock Output | Dedicated differential clock copy; fixed polarity, 45–55% duty cycle, synchronized to serialized data for receiver timing recovery. |
| R0–R7, G0–G7, B0–B7 | CMOS RGB Pixel Inputs | 24-bit parallel video bus; pin assignments reconfigurable via SWAP pin to simplify top/bottom PCB placement. |
| HS, VS, DE, PCLK | CMOS Timing Control Inputs | Standard video sync signals; all include failsafe logic to prevent damage during partial power-up sequences. |
| TXEN | Transmitter Enable Input | Glitch-suppressed (≥10 μs pulse required); controls full shutdown (0.5 μA) or active transmission with 0.24 ms wake-up latency. |
| LS0, LS1 | Link Select Configuration | Two-pin encoding selects 1/2/3 active SubLVDS links and sets PLL bandwidth range (e.g., LS0=0/LS1=1 → 3-channel, 7.0% BW @ 65 MHz). |
Key Features
| Feature | Design Value |
|---|---|
| Programmable 1/2/3-Channel SubLVDS Output | Enables scalable bandwidth allocation: 1-channel for QVGA, 2-channel for VGA, 3-channel for XGA+ - reducing FPC pin count and EMI without redesigning the display interface. |
| Odd-Parity Bit Insertion | Adds single-bit error detection to the 30-bit serialized word (27 data + 1 parity + 2 reserved), allowing downstream receivers like SN65LVDS302 to flag corrupted pixel transfers. |
| Bus Swap (SWAP Pin) | Reverses RGB data pin order (R0–R7 ↔ B0–B7), permitting identical PCB layouts for top-side or bottom-side component placement - cutting NRE costs in dual-sided flex designs. |
| Failsafe CMOS Inputs | Guarantees safe operation during power ramp-up: all inputs tolerate 2.165 V while VDD remains below 1.65 V, eliminating need for external level-shifters or sequencing controllers. |
| SAE J1752/3 'M'-Spec Compliance | Meets stringent automotive electromagnetic emission limits (≤12 dBµV at 777–988 MHz) - validated across all link modes, enabling use in certified infotainment and HUD displays. |

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 |
|---|---|---|---|
| SN65LVDS311ZQE | Same 80-pin nFBGA package and 1.8-V supply, but supports only 2-channel SubLVDS output (no 3-channel mode); lower max PCLK (45 MHz) and throughput (1350 Mbps). | Targeted at VGA-class displays only; lacks XGA+ support and higher-bandwidth timing margin for future-proofing. | Select when cost optimization is prioritized over scalability and maximum resolution headroom. |
| SN65LVDS302ZQE | Complementary FlatLink3G receiver (not transmitter); pin-compatible with SN65LVDS301ZQE on differential I/O side but functionally opposite (serial-to-parallel). | Used exclusively on display panel side; cannot substitute for SN65LVDS301ZQE in source-side serialization. | Required as paired receiver in full FlatLink3G link design; not a functional alternative but a mandatory companion device. |
Compared with SN65LVDS311ZQE, the SN65LVDS301ZQE offers higher resolution scalability (XGA+), greater EMI margin, and flexible link configuration - making it preferable for next-generation portable displays. SN65LVDS302ZQE is not a replacement but the designated receiver partner, ensuring end-to-end timing alignment and error detection interoperability.

FAQ
What is the maximum pixel clock frequency supported by the SN65LVDS301ZQE in 3-channel mode?
The SN65LVDS301ZQE supports a maximum pixel clock frequency of 65 MHz in 3-channel mode, enabling serialized data throughput up to 1755 Mbps. This allows driving XGA+ (1024×768) and higher-resolution displays with tight timing margins, as confirmed in Section 6.3 and Figure 6-6 of the official datasheet.
Does the SN65LVDS301ZQE require external termination resistors for its SubLVDS outputs?
No, the SN65LVDS301ZQE does not require external termination resistors. Its SubLVDS outputs are internally matched to 100 Ω differential impedance (ZOD(CLK) = 210 Ω specified, consistent with industry-standard SubLVDS driver design), and the recommended load is 100 Ω across D+/D− pairs as defined in Figure 7-3 of the datasheet.
How does the bus swap (SWAP) feature affect PCB layout for the SN65LVDS301ZQE?
The SWAP pin on the SN65LVDS301ZQE reverses the assignment of RGB data pins (e.g., R0↔B7), allowing identical PCB footprints to accommodate either top-side or bottom-side component placement on flex or rigid-flex boards. This eliminates the need for separate layout variants and reduces NRE costs in dual-sided display module designs.
What is the purpose of the parity bit in the SN65LVDS301ZQE's 30-bit serialized word?
The SN65LVDS301ZQE inserts an odd-parity bit into each 30-bit word (27 data bits + 1 parity + 2 reserved), enabling downstream receivers like the SN65LVDS302ZQE to detect single-bit errors in transmitted pixel or control data. This enhances display data integrity without requiring protocol-level retransmission mechanisms.
Can the SN65LVDS301ZQE operate with a pixel clock below 4 MHz?
Yes - the SN65LVDS301ZQE enters standby mode for pixel clock frequencies below 500 kHz and fully shuts down below that threshold. Between 500 kHz and 3 MHz, behavior is unspecified; operation is guaranteed only within the recommended 4–65 MHz range. For low-frequency use cases, designers must validate timing and power states empirically per Section 6.3 Note 2.
