■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.
■FEATURES

*The dissipation pad for the USP-6B package
should be solder-plated in recommended mount
pattern and metal masking so as to enhance
mounting strength and heat release.
If the pad needs to be connected to other pins,
it should be connected to the V
