Features
- Serial programming: Feedback and reference divisors, VCO gain, phase comparator gain, relative phase and test modes.
- Supports high-resolution graphics - Differential CLK out-puts to 230 MHz
- Eliminates need for multiple ECL output voltage controlled crystal oscillators and external components
- Fully-programmable synthesizer capability - 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 switchover to internal feedback
- Small footprint 24-pin SOIC
- Coarse and fine phase adjustment permits precise clocking in video recovery application
Description
The 1522 is a very high performance monolithic phaselocked loop (PLL) frequency synthesizer. Utilizing ICS's advanced CMOS mixed-mode technology, the 1522 provides a low-cost solution for high-end video clock generation where synchronization to an external video source is required. The 1522 has differential video clock outputs (CLK+ and CLK-) that are compatible with industry standard video DAC. Operating frequencies are fully programmable with direct control provided for reference divider, feedback divider and postscaler.

Single Phase Energy meter
Hello All Last month I saw Renesa's new RA series, and I found it is a very good feature. Now I am designing one Single-phase Energy Meter and it also has some control feature as well so I Won't some powerful controller so I was selected RX21A ...

Config of SPI MOSI Pin level at idle for RL78/F14
I'm using the RL78 R5F10PGG (48-pin) SPI module. Everything behaves as expected except that the SDO line seems to have an idle state of low so that the SDO pin is held low whenever data is not transmitted. I would like the SDO pin to remain high unless ...

External RAM recommendations
Hi, I use the S5D9 with GUIX and I need more RAM than the internal 640kB for storing GUIX display buffers. Can anybody recommend me the right RAM chip(s) to use as external RAM. At least 8Mbit / 1MbyteCorrect speed, fast enough so that it doesn’t bottleneck the ...
