ICS1562B

The ICS1562B is a very high performance monolithic phaselocked loop (PLL) frequency synthesizer. Utilizing ICS's advanced CMOS mixed-mode technology, the ICS1562B provides a low cost solution for high-end video clock generation.

The ICS1562B has differential video clock outputs (CLK+ and CLK-) that are compatible with industry standard video DAC. Another clock output, LOAD, is provided whose frequency is derived from the main clock by a programmable divider.

An additional clock output of the ICS1562B is available, LD/N2, which is derived from the LOAD frequency and whose modulus may also be programmed. Operating frequencies are fully programmable with direct control provided for reference divider, prescaler, feedback divider and post-scaler. Reset of the pipeline delay on Brooktree RAMDACs may be performed under register control. Outputs may also be set to desired states to facilitate circuit board testing.
