Description
The ICS1574B is a very high performance monolithic phase-
locked loop (PLL) frequency synthesizer designed for laser
engine applications. Utilizing ICS’s advanced CMOS mixed-
mode technology, the ICS1574B provides a low cost solution
for high-end pixel clock generation for a variety of laser en-
gine product applications.
The pixel clock output (PCLK) frequency is derived from the
main clock by a programmable resettable divider.
Operating frequencies are fully programmable with direct
control provided for reference divider, feedback divider and
post-scaler.
