XC25BS5 Series
ETR1502_003a
PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits
(For Low Frequency Range)
GENERAL DESCRIPTIO N
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 freque ncy/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 o ne of
high-impedance.
■APPLICATIONS
●Crystal oscillation modules
●Personal computers
●PDAs
●Portable audio systems
●Various system clocks

*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
