Integrated Circuit Systems ICS1574B
The ICS1574B is a very high performance monolithic phaselocked loop (PLL) frequency synthesizer designed for laser engine applications. The pixel clock output (PCLK) frequency is derived from the main clock by a programmable resettable divider. Utilizing ICS’s advanced CMOS mixedmode technology, the ICS1574B provides a low cost solution for high-end pixel clock generation for a variety of laser engine product applications.| Part No. | ICS1574B |
