XC25BS7

XC25BS7 Series is Not Recommended for New Designs. XC25BS7 Series PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits ETR1505-009 ■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. ■ APPLICATIONS ● Clock for controlling an Imaging dot ● Microcomputer and HDD drives ● Cordless phones ● Wireless communication equipment ● PDAs ● Cameras, VCRs ● Various system clocks ■FEATURES Input Frequency : 32kHz ~ 36MHz (*1) Output Frequency : 1MHz ~ 100MHz (fQ0=fCLKin × N/M) (*1) Output Divider (N) : Selectable from divisions from 1 to 256 (*1) Input Divider (M) : Selectabl...
