TLV3605 800 ps High-Speed Rail-Rail Input Comparator

Texas Instruments' TLV3605 is an 800 ps, high-speed comparator with LVDS outputs, rail-to-rail inputs, an operating voltage range of 2.4 V to 5.5 V, and a high toggle frequency of 3 Gbps. These features make the TLV3605 well-suited for LIDAR, clock and data recovery applications, and test and measurement systems. The TLV3605 has a strong input overdrive performance of 350 ps and can detect narrow pulse widths of 600 ps. This combination of low variation in propagation delay due to input overdrive and the ability to detect narrow pulses improve system performance and extend distance range in time-of-flight (ToF) applications.

The low-voltage-differential-signal (LVDS) output helps increase data throughput and optimizes power consumption. The complementary outputs reduce EMI by suppressing common-mode noise on each output. The LVDS output is designed to drive and interface directly with downstream devices that accept a standard LVDS input such as high-speed FPGAs and CPUs. The TLV3605 maintains the same performance as the TLV3604, and offers adjustable hysteresis control, shutdown, and latching features in a 12-pin QFN package making it an excellent choice for test and measurement applications.
