Product details

Lifecycle status is Active.

Industrial temp and tight stability for serial links

Frequency stability is ±25 ppm, tight enough for PCIe Gen1–3, SATA, and 1GbE reference clocks without requiring a TCXO or OCXO. Supply voltage range is 2.25 V to 3.6 V, allowing a single oscillator to work across 2.5 V and 3.3 V rails without a separate regulator.

6-SMD package — board layout fit

Housed in a 6-SMD, No Lead package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The 6-pin footprint is common across the DSC1124 family — the enable/disable function is on pin 1, output on pin 4, and the remaining pins are supply and ground.

Frequently asked questions

How can I order DSC1124AI2-100.0000T or request a quote?

The part is Active and available through independent distribution. No stock-holding claim; sourced per order.

What is the frequency stability of DSC1124AI2-100.0000T?

±25 ppm. This is sufficient for PCIe Gen1–3, SATA, and 1GbE reference clocks without needing a TCXO or OCXO.

Is DSC1124AI2-100.0000T a direct replacement for other 100 MHz HCSL oscillators?

The DSC1124AI2-100.0000T is a MEMS-based XO with HCSL output. Pin-compatible quartz-based HCSL oscillators exist, but the MEMS resonator eliminates crystal aging and offers better vibration immunity. Confirm the footprint (6-SMD, No Lead) and supply voltage range (2.25 V to 3.6 V) match your BOM before substituting.

How do I enable/disable the output on DSC1124AI2?

The enable/disable function is on pin 1. Pulling it low disables the output to high-Z; pulling it high or leaving it floating enables the output. Disable current drops to 22 mA max.

Is DSC1124AI2-100.0000T RoHS compliant?

The part is supplied in a 6-SMD, No Lead package and is listed as RoHS-compliant per Microchip's standard material declaration for the DSC1124 series.
