Typical Applications
TLV3801 is suitable for 6 applications: LIDAR Systems, Differential Line Receivers, Optical Sensor Modules, Clock Recovery, Test and Measurement, Automotive Radar.
LIDAR Systems
The TLV3801's 225-ps propagation delay and 3 GHz toggle frequency enable precise detection of narrow laser pulses in LIDAR systems. Its LVDS outputs interface directly with FPGAs for time-of-flight calculations, and the small 8-WSON package fits compact optical modules. The wide supply range supports 3.3 V or 5 V systems, and the low power consumption is ideal for battery-powered or thermal-sensitive designs.
Recommended
Differential Line Receivers
The TLV3801 can be used as a differential line receiver for high-speed data transmission. Its LVDS outputs provide a direct interface to FPGAs or CPUs, and the complementary outputs reduce EMI. The 225-ps propagation delay ensures minimal skew in high-speed serial links, and the 3 GHz toggle frequency supports data rates up to 3 Gbps. The device operates from a single 3.3 V supply, simplifying power design.
Recommended
Optical Sensor Modules
The TLV3801 is ideal for optical sensor modules due to its small 8-WSON package and high-speed performance. It can detect fast optical pulses from photodiodes, and its LVDS outputs drive digital processing circuits. The low power consumption is beneficial for portable devices, and the wide supply range allows operation from a single lithium-ion cell. The enable pin can be used for power gating to extend battery life.
Recommended
Clock Recovery
The TLV3801 can be used in clock recovery circuits to extract timing information from high-speed data streams. Its fast propagation delay and high toggle frequency allow it to track rapid signal transitions, and the LVDS outputs provide clean digital levels for PLLs or FPGAs. The complementary outputs help maintain signal integrity, and the device's low jitter is critical for accurate clock recovery.
Recommended
Test and Measurement
In test and measurement equipment, the TLV3801 provides fast edge detection for oscilloscope triggers and logic analyzers. Its 225-ps propagation delay ensures accurate timing measurements, and the 3 GHz toggle frequency allows capture of high-frequency signals. The LVDS outputs interface with acquisition systems, and the small package enables dense channel counts. The wide supply range supports various logic levels.
Recommended
Automotive Radar
The TLV3801 is suitable for automotive radar systems where fast signal processing is required. Its AEC-Q100 qualified variant (TLV3801QDSGRQ1) ensures reliability in harsh environments. The 225-ps propagation delay enables rapid detection of radar pulses, and the LVDS outputs interface with DSPs or FPGAs. The wide supply range and small package make it easy to integrate into radar modules.

Design Notes
Place 0.1 µF decoupling capacitors as close as possible to the VCC and GND pins. Use a solid ground plane and minimize trace lengths to reduce parasitic inductance. For LVDS outputs, route as differential pairs with 100 Ω differential impedance and terminate with 100 Ω resistors at the receiver.
The TLV3801 consumes approximately 6.5 mA at 3.3 V, resulting in 21.5 mW power dissipation. Ensure the power supply can handle this load and provide adequate decoupling. The wide supply range allows operation from 2.7 V to 5.25 V, but verify the input common-mode range for your specific supply voltage.
Do not exceed the absolute maximum supply voltage of 5.5 V. The LVDS outputs must be terminated with 100 Ω differential impedance to prevent reflections. The enable pin is active high; leave it floating or tie to VCC for normal operation. Ensure the input signals are within the common-mode range to avoid false triggering.
