The 1574B is a very high performance monolithic phaselocked loop (PLL) frequency synthesizer designed for laser engine applications. Utilizing ICS's advanced CMOS mixedmode technology, the 1574B provides a low cost solution for high-end pixel clock generation for a variety of laser engine 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.
