Integrated Circuit Systems, Inc. ICS1567 Differential Output Video Dot Clock Generator General Description The ICS1567 is a very high performance monolithic PLL frequency synthesizer. Utilizing ICS’s advanced CMOS mixed-mode technology, the ICS1567 provides a low cost solution for high-end video clock generation, and for telecom system clock generation. The ICS1567 has differential video clock outputs (CLK and CLK) that are compatible with industry standard video DACs & RAMDACs. An additional clock output, LD, is provided, whose frequency is divided down from the main clock by a programmable divider. Operating frequencies are selectable from a pre-programmed (customer-defined) table. An on-chip crystal oscillator for generating the reference frequency is provided on the ICS1567.
