  Hello, Time-Nutters--

A friend pointed me to an interesting chip for time
interval measurement and related time and temperature
measurement functions:

A general purpose TDC: The TDC-GP2

I think the chip is around $20 in single-unit quantity.


Measurement range 3.5 ns to 1.8 us

2 channels with resolution of 50 ps

4 events can be measured against each other

15 ns pulse-pair resolution

It also has a temperature measurement function:

2 or 4 sensors

16 bit resolution

0.004 Deg C resolution for platinum sensors
