Product details

MEMS dual-frequency XO for video-timing applications

The DSC6121HI2A-00AJ: These frequencies match the standard pixel clocks for 1080p video at 59.94 Hz and 60 Hz respectively, making this part a natural fit for HDMI, DisplayPort, or broadcast-video timing chains where a single oscillator must cover both frame rates.

Industrial temperature grade and stability

The CMOS output swings rail-to-rail and drives standard logic inputs directly; no termination or level translation is needed when the supply matches the downstream IC's I/O voltage.

Obsolete — sourcing through independent channels

For existing BOM lines, this part is available through independent surplus and broker channels.
