Low Refresh Rate PLL for Video and Flat Panel Display Drivers

CEVA has developed a high performance PLL IP Core for use in Video and Flat Panel Display Applications that use the standard horizontal rate frequency to generate the required Pixel Rate Clock. Capable of accepting horizontal rate frequencies from 15 KHz to 110 KHz and providing pixel rates from 13 MHz to 230 MHz the CEVA Low Refresh PLL can accommodate many standard modes including VGA, SVGA, XGA, SXGA, UXGA, NTSC and a range of other modes. The core also includes a 16 step phase adjust mechanism used to deskew channels.

CEVA’s patented design controls phase drift maintaining typically <1ns input to output drift in most standard modes.

Proven in a number of processes including the TSMC 0.25um and a proprietary 0.13um IDM process the Low Refresh PLL has proved robust and portable across processes and geometry size.
