Product details

MEMS resonator, LVDS output — what this oscillator delivers

The MEMS resonator eliminates quartz-crystal startup issues and vibration sensitivity, while the LVDS output provides low-jitter differential signalling for high-speed digital loads.

Microchip lists the DSC1123AI2-040.0000T as Active.

Packaging and supply chain fit

The 6-SMD, No Lead Exposed Pad package (7.00 mm x 5.00 mm footprint, 0.90 mm seated height) is a standard oscillator footprint — no special paste stencil or via-in-pad requirements.

Frequently asked questions

What output logic does the DSC1123AI2-040.0000T provide?

It outputs LVDS (Low-Voltage Differential Signalling), which is a differential pair requiring 100-ohm termination at the receiver. This makes it suitable for driving clock inputs on FPGAs, high-speed ADCs, and Gigabit Ethernet PHYs.

Can the DSC1123AI2-040.0000T replace the DSC1123AI2-025.0000T?

Both are from the same DSC1123 series and share the same package, supply range, and temperature grade. The only difference is frequency: 40 MHz vs 25 MHz. If your BOM calls for 40 MHz, this part is a direct drop-in for the 25 MHz variant in terms of footprint and electrical interface.
