ICS1522 Description
The ICS1522 is a very high performance monolithic phaselocked loop (PLL) frequency synthesizer. Utilizing ICS’s advanced CMOS mixed-mode technology, the ICS1522 provides a low-cost solution for high-end video clock generation where synchronization to an external video source is required. The ICS1522 has differential video clock outputs (CLK+ and CLK- ) that are patible with industry standard video DAC.
ICS1522 Key Features
- Serial programming: Feedback and reference divisors, VCO gain, phase parator gain, relative phase and test modes. Suppor
- Differential CLK out-puts to 230 MHz Eliminates need for multiple ECL output voltage controlled crystal oscillators and
- not just a clock multiplier Line-locked clock generation capability; 15
- 100 kHz External feedback loop capability allows graphics system to be used as the feedback divisor with synchronous swi
