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

Applications 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 range beyond the swing input it is ideal for low voltage applications Rail to rail output can directly drive CMOS or TTL logic This module can reshape a wide voltage range 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 The major feature of this module sine wave square wave and triangle wave can be shaped without threshold setting and become square wave which is convenient to use and does not need debugging At the same time it has good scalability and only needs to modify a few originals Technical indicators 1 Supply voltage 2 7 5VDC2 Input voltage 8 1000mV effective value 3 Output level Rail to rail output can directly drive TTL CMOS level4 Input frequency 1Hz 120MHz as small as 1Hz5 Interface form SMA female external screw inner hole 6 Input impedance 20K ohm Product use 1 Sine wave to square wave2 Zero crossing comparator3 General purpose comparatorPackage includes 1 x Frequency Meter
