Product details

Dual-frequency MEMS XO — 22.5792 MHz and 24.576 MHz

The DSC6121CE2A-0081T: These frequencies are the standard audio and video clock rates — 22.5792 MHz for 44.1 kHz sample-rate families and 24.576 MHz for 48 kHz families — making this oscillator a natural fit for HDMI, USB audio, or codec reference clock trees where both domains coexist on one board.

Frequency stability and temperature range

Rated ±25 ppm frequency stability over -20°C to +70°C — sufficient for audio/video jitter budgets in consumer and industrial environments where the ambient stays within this band.

Obsolete — sourcing through independent channels

The part is available through independent surplus and broker channels.

Frequently asked questions

What are the two output frequencies of the DSC6121CE2A-0081T?

The oscillator outputs 22.5792 MHz and 24.576 MHz simultaneously as CMOS signals. These correspond to the standard audio sample-rate clock (22.5792 MHz for 44.1 kHz families) and the video/audio clock (24.576 MHz for 48 kHz families).
