SD & HD Video Timing
The VFCG-HD1 is a fully integrated video clock generator which provides synchronous High Definition (HD) and Standard Definition (SD) output clocks for the various scanning formats. The device synchronizes to the standard input reference clock required by SMPTE274, SMPTE296, NTSC, or PAL systems. A 5-bit address is used to synchronize the generator to the appropriate input reference clock. A dedicated control signal divides the maximum HD clock rate by 2 in order to support HD clock rates of 74.25 MHz and 74.1758 MHz.
