Texas Instruments announces High-Speed RRI Comparator with LVDS Outputs

Texas Instruments TLV3604 TLV3605

Texas Instruments has announced TLV3604 and TLV3605 800-ps, high-speed comparators with LVDS outputs and rail-to-rail inputs. These features, along with an operating voltage range of 2.4 V to 5.5 V and a high toggle frequency of 3 Gbps, make the TLV3604 and TLV3605 well suited for LIDAR, clock and data recovery applications, and test and measurement systems.

Likewise, the TLV3604 and TLV3605 have strong input overdrive performance of 350 ps and are able to detect narrow pulse widths of just 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-Signaling (LVDS) output of the TLV3604 and TLV3605 also 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 TLV3604 is in a tiny 6 pin SC-70 package, which makes it easier for space sensitive applications such as an optical sensor module. 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.
