XC25BS8 Series
ETR15006-011
Ultra-Small PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits
■GENERAL DESCRIPTION
The XC25BS8 series is an ultra small PLL clock generator IC which can generate a high multiplier output up to 4095 from an input frequency as low as 8kHz. The series includes a divider circuit, phase/frequency comparator, charge pump, and VCO so it is possible to configure a fully operational circuit with a few external components like one low-pass filter capacitor. The Input divider ratio (M) can be selected from a range of 1 to 2047, the output divider ratio (N) can be selected from a range of 1 to 4095 and they are set internally by using laser timing technologies.
