3 Description

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.
