Texas Instruments TLV3811CYBGR

Overview

TLV3811CYBGR from Texas Instruments is a 225-ps propagation delay, single-channel high-speed comparator with LVDS differential outputs, 1.1-mV internal hysteresis, and 240-ps minimum input pulse width detection capability. It operates from a single 2.7 V to 5.25 V supply and delivers 3 GHz toggle frequency (6 Gbps) for precision timing in optical time-of-flight and LIDAR front-ends.

For engineers reviewing the TLV3811CYBGR datasheet, TLV3811CYBGR pinout, TLV3811CYBGR application, or TLV3811CYBGR equivalent, this device is selected where sub-nanosecond timing fidelity, low overdrive dispersion (5 ps), and space-constrained DSBGA packaging are critical - especially in drone vision sensors and high-resolution distance sensing modules.

Technical Context

The TLV3811CYBGR uses a fully differential LVDS output stage referenced to GND, enabling direct interface with FPGA and ASIC LVDS receivers without level-shifting. Its input stage supports common-mode voltages from GND + 1.5 V to VCC + 0.1 V and features ±0.5 mV input offset voltage with 80 dB CMRR and PSRR.

Unlike the WSON-packaged TLV3801/TLV3802, the TLV3811CYBGR integrates both input and output power domains onto a single supply rail (VCC–GND), eliminating VEE and simplifying PCB routing. Its 6-pin DSBGA package (1.218 mm × 0.818 mm) mandates strict thermal management due to 132.1°C/W junction-to-ambient resistance.

FAQ

What is the supply voltage range for TLV3811CYBGR?

The TLV3811CYBGR operates from a single 2.7 V to 5.25 V supply referenced between VCC and GND. It does not require a negative rail (VEE), unlike the TLV3801/TLV3802 family. This simplifies power design in space-constrained optical modules where TLV3811CYBGR is commonly deployed.

Does TLV3811CYBGR support differential input signals?

Yes, TLV3811CYBGR accepts true differential inputs across IN+ and IN− with a specified differential input voltage range of ±1.5 V. Its input stage maintains 80 dB CMRR and supports common-mode voltages from GND + 1.5 V to VCC + 0.1 V - essential for rejecting noise in photodiode amplifier interfaces used with TLV3811CYBGR.

What is the purpose of the 1.1-mV hysteresis in TLV3811CYBGR?

The 1.1-mV internal hysteresis in TLV3811CYBGR provides noise immunity for optical pulse detection without sacrificing sensitivity to weak return signals. It prevents output chatter during slow-rising or noisy input transitions - a critical feature for reliable operation in drone-mounted LIDAR where TLV3811CYBGR processes ambient-light-contaminated waveforms.

Can TLV3811CYBGR drive standard LVDS loads directly?

Yes, TLV3811CYBGR's LVDS outputs are compliant with ANSI TIA/EIA-644 and deliver ±350 mV differential swing into a 100 Ω load terminated at 1.25 V common-mode voltage. This allows direct connection to FPGA LVDS inputs (e.g., Xilinx Artix-7) without external biasing or level-shifting circuitry - a key advantage of TLV3811CYBGR in high-speed digital interfaces.

How does TLV3811CYBGR differ from TLV3801 in terms of power architecture?

TLV3811CYBGR uses a single-supply architecture (VCC–GND) for both input and LVDS output stages, whereas TLV3801 requires dual supplies (VCC–VEE for inputs, VCC–GND for outputs). This eliminates VEE routing complexity and reduces component count in designs using TLV3811CYBGR - particularly beneficial in compact optical sensor modules.
