M66238FP
Standard Clock Generator with PLL Frequency Synthesizer
REJ03F0268-0200
Rev.2.00
Mar 18, 2008
Description
The M66238 is a LSI that incorporates a PLL synthesizer and a sync clock generator in it. The PLL synthesizer covers
the range of 25 MHz to 50 MHz at the minimum steps of 3 kHz.
The sync circuit outputs a clock and a one-shot pulse which are synchronized with an external trigger signal. Setting a
dividing ratio allows acquisition of sync clock outputs within the range of 0.78 MHz to 25 MHz.
Features
Sync clock output frequency range: 1/1, 1/2, 1/4, 1/8, 1/16, 1/32 of 25 to 50 MHz
Sync accuracy (jitter): ±3 ns
Trigger input: Polarity selectable
One-shot pulse output: Polarity and width selectable
5 V power supply
