3pcs TLV3501 High-speed Waveform Comparator Frequency Meter Tester Front-end Shaping Module

The TLV3501 is a single-channel high-speed push-pull output comparator with a delay time of 4.5ns and a supply voltage: + 2.7V to + 5.5V. With an input common-mode  beyond the swing input, it is  for low-voltage applications. Rail-to-rail output can directly drive CMOS or TTL logic. This module can reshape a wide voltage  periodic signal. It can be used as a front-end conditioning module for time domain measurements such as frequency and phase difference. It can also be used as a front-end module for the digital frequency meter of the 2015 National College Student Electronic Design Competition.

Features:

The sine , square , and triangle  can be shaped without setting thresholds, and turned into a square , which is convenient to use and does not require debugging. At the same time, it has good scalability and only needs to modify a small number of originals.

Technical indicators:

1. Supply voltage: 2.7-5VDC

2. Input voltage: 8-1000mV (effective value)

3. Output level: Rail-to-rail output, can directly drive TTL / CMOS level

4. Input frequency: 1Hz--120MHz, as small as 1Hz

5. Interface form: SMA female (external screw inner hole)

6. Input impedance: 20K ohm
