Parallel Mode Operation
Table 3-21: ICS8442 Divisor Switch Settings
Each clock synthesizer has one set of subminiature DIP switches to set the multiplier and
divider settings in parallel mode. Clock Synthesizer 1, with a 10 MHz reference clock
input, can be set to 0x019 through 0x046, as shown in
Synthesizer 2, with a 25 MHz reference clock input, can be set to 0x00A through 0x01C, as
shown in
selection of multiplier values that result in valid VCO lock ranges. Multiplier bits that
would result in a VCO unlock condition are hardwired to a logic 0 level on the board.
Notes:
1. A logic “0” is obtained by moving the switch to the “OPEN” position, and a logic “1” is obtained by
