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 25MHz to 50MHz at the minimum steps of 3kHz.

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 0.78MHz to 25MHz.

FEATURES

• Sync clock output frequency range: 1/1, 1/2, 1/4, 1/8, 1/16, 1/32 of 25 to 50MHz

• Sync accuracy (jitter): ±3ns

• Trigger input: Polarity selectable

• One-shot pulse output: Polarity and width selectable

• 5V power supply

APPLICATION

Pixel clock generator
