Hello all:
I have a 6.144Mhz crystal and I am trying to generate the 9600*16 ~ 154k clock needed by the
8251 UART and the ~ 1Mhz system clock.I dont want to use the 74ls* series ripple counters and I have a bunch of 22v10 PAL chips lying around.
I have been thinking about how best to do this, using what I have.
Basically I need to divide the 6.144Mhz by 40. First by 5 to realize the system clock, then by
8 to realize the UART baud clock.With the 22v10 I could set aside two 3 bit "registered" outputs for a GLITCH FREE synchronous counter ... But I would need the output of one to drive the other ... and I dont see how I can do this when they all share a common CLK input.
By the way I also have a bunch of 74ls112 dual J/K flip flops lying around (about 25). I thought I might use that along with the 22v10' to realize my clock divider.
Any ideas?
