XC25BS7 Series
PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits
www.DataSheet4U.com
ETR1505-007a
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.

*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.

NOTE:
*1: Connected CIN=0.1 F of a ceramic capacitor between the VDD pin the VSS pin while testing.
*2: Time until signal via the Q0 pin flows stably from applying supply voltage to the VDD pin and control voltage to the CE pin while
applying the input signal to the CLKin pin.
*3: The value indicated at output start time is designed values which are not guaranteed values.
