Integrated Circuit Systems, Inc. ICS1562B User Programmable Differential Output Graphics Clock Generator Description 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 is available, LD/N2, which is derived from the LOAD frequency and whose modulus may also be programmed.
