■General Description
The XC25BS5 series are high frequency, low power consumption PLL
clock generator ICs with divider circuit & multiplier PLL circuit.
Laser trimming gives the option of being able to select from divider ratios
(M) of 1,3 to 2047 and multiplier ratios (N) of 6 to 2047.
Output frequency (Q0) is equal to reference oscillation (fCLKin)
multiplied by N/M, within a range of 3MHz to 30MHz. Q1 output is
selectable from input reference frequency (f0), input reference
frequency/2 (f0/2), ground (GND), and comparative frequency (f0/M).
Further, comparative frequencies, within a range of 12KHz to 500KHz,
can be obtained by dividing the reference oscillation. By halting
operation via the CE pin, consumption current can be controlled and
output will be one of high-impedance.
