MEMS XO with dual video-frequency outputs
The DSC6023CI2A-00A7: This pair is the standard clock reference for SD and HD video formats — the 74.1758 MHz drives 59.94 Hz frame-rate systems, while 74.25 MHz serves the 60 Hz variant. A single oscillator covers both standards without a second PLL or external mux.
This holds the pixel clock jitter within one line of a 1080p60 stream without external temperature compensation.
Obsolete — sourcing through independent channels
No direct pin-compatible successor is listed on the official record. For new designs, consider the active DSC60XX family variants with matching frequency options and the same 4-VDFN footprint.
4-VDFN package — board-fit note
The land pattern matches standard 4-pin oscillator footprints — no layout change from a quartz XO in the same package. The MEMS die eliminates the quartz crystal's start-up time; output is valid within microseconds of power-on.
