Description:
and Data Inputs
Test 1
This test verifies the setup and hold times for the falling edge of the HP 1652B
L clock specification, and the falling edge of the HP 1653B J and K clock
specification. This test also verifies the maximum clock rate with counting mode
on.
Specification:
Clock repetition rate: With time or state counting mode on, minimum time
between states is 60 ns.
Setup time: Data must be present prior to the clock transition, > 10 ns.
*HP 1652B hold time: Data must be present after the falling edge of the L clock
transition, 0 ns.
HP 1653B hold time: Data must be present after the falling edge of the J and K
clock transition, 0 ns.
