Product details

MEMS oscillator with HCSL output and automotive qualification

The DSC8124AI2: The HCSL (High-Speed Current Steering Logic) differential output is a common interface for PCIe reference clocks and high-speed serial links, delivering low jitter and controlled edge rates without external termination resistors. The MEMS resonator inherently withstands shock and vibration better than quartz-based oscillators, and the device starts up in under 5 ms typical.

Supply voltage and frequency stability

The wide input range simplifies power tree design in mixed-voltage systems. Maximum supply current is 42 mA at full frequency; disabling the output (Enable/Disable pin) drops consumption to 22 mA max. For applications requiring better than ±25 ppm (e.g., SyncE or IEEE 1588), a TCXO or OCXO would be needed.

Programming and packaging

The DSC8124AI2 ships as a blank (unprogrammed) device — the user must program the target frequency using Microchip's TimeFlash or a compatible programmer before assembly. This allows a single stock-keeping unit to cover multiple frequency requirements, reducing inventory complexity. Supplied in tube packaging.

Frequently asked questions

What is the output type of the DSC8124AI2?

The DSC8124AI2 outputs HCSL (High-Speed Current Steering Logic), a differential current-mode logic level commonly used for PCIe reference clocks and high-speed serial interfaces. The receiver must be HCSL-compatible.

What is the available frequency range for the DSC8124AI2?

The DSC8124AI2 can be programmed to any frequency between 10 MHz and 460 MHz. Common frequencies include 100 MHz (PCIe Gen1/2/3) and 125 MHz (Ethernet).

Does the DSC8124AI2 require programming before use?

Yes, the device ships blank (unprogrammed). The user must program the target frequency using Microchip's TimeFlash programmer or a compatible tool before soldering the oscillator onto the PCB.
