Dual-frequency MEMS XO in a 1.6 x 1.2 mm footprint
The DSC6121HI2A-00AJT: These two frequencies are the standard pixel-clock rates for 1080p/59.94 Hz and 1080p/60 Hz video formats, respectively, making this oscillator a direct fit for broadcast video, HDMI, and display timing chains where both frame rates must be supported without a second crystal.
Industrial temperature range and low power draw
Typical supply current is 3 mA — low enough that the oscillator's contribution to the system thermal budget is negligible, even in fanless enclosures or battery-powered portable video equipment.
Obsolete — sourcing through independent channels
The MEMS resonator construction in the DSC61XX family offers inherent shock and vibration resistance compared to quartz-based oscillators — a useful reliability edge in portable or mobile video systems — but the obsolete status means any BOM line using this part should be reviewed for a drop-in alternative or a board-spin to a current Microchip MEMS XO family. No stock-holding claim — each lot is verified for marking consistency and package integrity before shipment.
