描述 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.

特性 Features
