The TLV3901 is a 125ps high speed comparator with a wide power supply range and a high toggle frequency of 11GHz. Along with an operating supply voltage range of 3.1V to 5.25V, the TLV3901 comes in an industry-standard small packages, making this comparator well suited for Time-of-Flight (ToF) applications such as LIDAR, differential line receivers, and test and measurement systems.

The TLV3901 has a strong input overdrive performance of 3ps and narrow pulse width capabilities of just 65ps. In addition to excellent performance specifications, the TLV3901 offers optional 50Ω on-chip termination resistors at both inputs along with latching function and programmable hysteresis features.

The Current-Mode-Logic (CML) output of the TLV3901 helps increase data throughput and optimizes power consumption. Likewise, the complementary outputs help to reduce EMI by suppressing common mode noise on each output. The CML output is designed to drive and interface directly with other devices that accept a standard CML input, such as most FPGAs and CPUs downstream in an application.

The TLV3901 is available in a 16-pin WQFN package which is desirable for space sensitive applications such as an optical sensor module.
