描述
The IDT1527 is a low-cost, high-performance frequency generator. It is suited to general purpose phase controlled clock synthesis as well as line locked and genlocked high-resolution video applications. Using IDT's advanced low-voltage CMOS mixed-mode technology, the IDT1527 is an effective clock synthesizer that supports video projectors and displays at resolutions from VGA to beyond XGA. The IDT1527 offers single-ended clock outputs to 60 or 110 MHz. The HSYNC_out, and VSYNC_out pins provide the regenerated versions of the HSYNC and VSYNC inputs synchronous to the CLK output. The advanced PLL uses either its internal programmable feedback divider or an external divider. The device is programmed by a standard I2C-bus™ serial interface and is available in a TSSOP16 package.
应用
- Frequency synthesis
- LCD monitors, video projectors and plasma displays
- Genlocking multiple video subsystems
