PCG8523
Programmable Clock Generator
IndustryPack®
The PCG8523 is a single-width Industry Pack with the following characteristics:-
This clock generator allows the user to select the frequency of a clock signal which is connected to one of the I/O lines of the IP card.
The first five bits in the clock frequency select register are used to select the clock frequencies of 1 Hz to 1MHz in multiples of 1, 2, 5 or 10. (E.g. 0=1Hz, 1=2Hz, 2=5Hz, 3=10Hz and so on to 15=100KHz, 16=200KHz, 17=500KHz, 18=1MHz).
A front panel lemo on all Newwood Solutions IP carrier cards connects to the IP STROBE line of the all the IP cards. This line can be used to start the clock by setting the relevant bit in 8623 the CSR.
