Texas Instruments TLV3811YBGR

Overview

TLV3811YBGR from Texas Instruments is a single-channel, 225-ps propagation delay high-speed comparator with LVDS output, internal 1.1 mV hysteresis, and 6-pin DSBGA (1.218 mm × 0.818 mm) package. It operates from 2.7 V to 5.25 V single supply, delivers 3 GHz toggle frequency / 6 Gbps data rate, and detects pulses as narrow as 240 ps - optimized for time-of-flight sensing in LIDAR and optical receiver front-ends.

For engineers reviewing the TLV3811YBGR datasheet, TLV3811YBGR pinout, TLV3811YBGR application, or TLV3811YBGR equivalent, key selection criteria include its ultra-low overdrive dispersion (5 ps), split input/output ground reference architecture, LVDS-compatible differential outputs driving standard FPGA inputs, and space-constrained suitability due to its sub-1-mm² DSBGA footprint.

Technical Context

The TLV3811YBGR employs a fully differential input stage referenced to GND (not split VEE), with input common-mode range from GND + 1.5 V to VCC + 0.1 V. Its LVDS output stage delivers ±350 mV differential swing at 1.25 V common-mode voltage into 100 Ω termination, enabling direct interface with FPGA and ASIC LVDS receivers without level-shifting.

Unlike the TLV380x series, TLV3811YBGR uses a single-supply architecture: VCC and GND only - no VEE pin. Its internal 1.1 mV hysteresis suppresses noise-induced chatter for medium-amplitude signals while preserving detection fidelity for fast, low-overdrive events typical in ToF and oscilloscope trigger applications.

Key Specifications

Pinout & Package

FAQ

What is the operating supply voltage range for TLV3811YBGR?

The TLV3811YBGR operates from a single supply of 2.7 V to 5.25 V referenced between VCC and GND. It does not require a negative supply (VEE) - unlike the TLV380x series - simplifying power design in compact optical modules where TLV3811YBGR is commonly deployed.

Does TLV3811YBGR support split-supply operation?

No, TLV3811YBGR does not support split-supply operation. Its input and output stages share a single GND reference. The TLV3801 and TLV3802 support split supplies via VEE, but TLV3811YBGR is strictly single-supply - confirmed in Section 7.3 and Table 6.4 of the datasheet. This architecture reduces pin count and PCB complexity for TLV3811YBGR applications.

What is the input hysteresis value of TLV3811YBGR?

The TLV3811YBGR has an internal input hysteresis of 1.1 mV, as specified in Section 6.5 (Electrical Characteristics) and Feature list of the datasheet. This is distinct from TLV3811CYBGR (0 mV) and TLV3801/TLV3802 (2 mV). The 1.1 mV hysteresis provides noise margin for medium-amplitude signals while preserving TLV3811YBGR's ability to resolve 240 ps pulses.

Can TLV3811YBGR drive standard FPGA LVDS inputs directly?

Yes, TLV3811YBGR LVDS outputs are fully compliant with ANSI TIA/EIA-644-A and deliver ±240–450 mV differential swing into a 100 Ω load, matching the input requirements of Xilinx Artix/Kintex and Intel Cyclone/Arria FPGAs. No external termination or level-shifting circuitry is needed when interfacing TLV3811YBGR with these devices.

What package type and dimensions does TLV3811YBGR use?

TLV3811YBGR uses a 6-pin DSBGA (YBG) package with nominal body size 1.218 mm × 0.818 mm and 0.4 mm ball pitch. This ultra-compact footprint is documented in the "Device Information" table and Figure 5-2 of the datasheet, making TLV3811YBGR suitable for space-constrained optical sensor modules where board area is at a premium.
