XC25BS7
Series
PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits
ETR1505-006
■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.
