■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

Output Frequency

: 3MHz ~ 30MHz (Q0=fCLKin×N/M)

Reference Oscillation (fCLKin)

: 12kHz ~ 35MHz

Divider Ratio (M)

Selectable from divisions of 1, 3~2047

Multiplier Ratio (N)

Selectable from multiplications of 6~2047

Output

: 3-State

output selectable from input reference

oscillation, input reference oscillation/2,

GND, comparative frequency.

Operating Voltage Range

: 2.97V ~ 5.5V

Low Power Consumption

(BOTTOM VIEW)

*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

pin.
