ICS650-27
For a 25 MHz fundamental crystal or clock input, the following four tables apply:
A Clocks Select Table (outputs in MHz)
C Clocks Select Table (outputs in MHz)
B Clocks Select Table (outputs in MHz)
Reference Output Clock Frequency (in MHz)
For a 12.5 MHz fundamental crystal or clock input, the following four tables apply:
A Clocks Select Table (outputs in MHz)
C Clocks Select Table (outputs in MHz)
B Clocks Select Table (outputs in MHz)
Reference Output Clock Frequency (in MHz)
0 = connect directly to GND
M = leave unconnected (automatically self biases to VDD/2)
1 = connect directly to VDD
