PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits
Series
1009
14
The XC25BS3 series are high frequency, low power consumption PLL
clock generator ICs with built-in crystal oscillator circuit, divider circuit &
multiplier PLL circuit.
Laser trimming gives the option of being able to select from divider ratios
(M) of 1 to 2047 and multiplier rations (N) of 20 to 2047.
Output frequency (Q0) is equal to reference oscillation (fCLKin)
multiplied by N/M, within a range of 9MHz to 80MHz. Q1 output is
selectable from input reference frequency (f0), Ground (GND), PLL
output frequency/2 (Q0/2), and comparative frequency/2 (f0/M/2).
Further, comparative frequency, within a range of 14KHz to 500KHz, can
be obtained by dividing the reference oscillation. By halting oscillation
via the CE pin, consumption current can be controlled. Output will be
one of high impedance.
