XC25BS7 Series

ETR1505-007a

PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits

GENERAL DESCRIPTION

The XC25BS7 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 input divider ratios (M) of 1 to 256 and output divider ratios (N) of 1 to 256. Output frequency (fQ0) is equal to reference clock oscillation (fCLKin) multiplied by N/M, within a range of 1MHz to 100MHz. Further, frequency within a range of 32kHz to 36MHz can be inputted as a reference clock. The IC stops operation when low level signal is inputted to the CE pin. For this, consumption current can be reduced and output will be one of high-impedance. Because the series is semi-custom, please ask Torex sales contacts for your requested specifications such as input/output frequency, supply voltage. However, the series has the limit of specifications; therefore, your request may not be fully satisfied with your requested frequency range.

TYPICAL APPLICATION CIRCUIT

*1: C

(by-pass capacitor, 0.1μF) should be connected to the

IN

IC as close as possible.

*2: Rq0 is a resistor for unwanted radiation only to use when

needed.

FEATURES

(*1)

Input Frequency : 32kHz ~ 36MHz

Output Frequency : 1MHz ~ 100MHz

(fQ0=fCLKin × N/M)

Output Divider (N) : Selectable from divisions

from 1 to 256

Input Divider (M) : Selectable from divisions

from 1 to 256

Operating Voltage Range : 2.50V ~ 5.50V

Low Power Consumption : CMOS with stand-by function

(10μA, MAX. when stand-by)

Packages Environmentally Friendly

*1: The series are semi-custom products. Specifications for

each product are limited within the above range. The input

frequency range is set within ±5％ of customer’s designated

typical frequency.

*2: When the IC is in stand-by mode, the output becomes high

impedance and the IC stops operation.

: SOT-25, USP-6C :EU RoHS Compliant, Pb Free
