Product details

MEMS oscillator with LVPECL output at 50 MHz

LVPECL provides low-jitter differential signaling ideal for high-speed serial interfaces like Gigabit Ethernet or PCIe reference clocks, where single-ended CMOS would introduce too much phase noise. Supply voltage spans 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail — no extra LDO needed for the oscillator alone.

Standby function for power-sensitive designs

The active supply current is 58 mA max, typical for a 50 MHz LVPECL output driving a 50-ohm terminated line.

Housed in a 6-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm.

Frequently asked questions

What is the closest pin-compatible alternative to DSC1102DI1-050.0000T?

Within the DSC1102 series, other frequency variants share the same 6-SMD footprint and pinout — for example, DSC1102DI1-100.0000T (100 MHz) or DSC1102DI1-125.0000T (125 MHz). For a different output type (e.g., LVDS or HCSL), look at the DSC1122 or DSC1132 series from Microchip, which are also MEMS-based and pin-compatible in the same package.

Does DSC1102DI1-050.0000T have a standby function and how does it work?

Yes, the Standby (Power Down) pin disables the output and drops supply current to 95 µA max. When the pin is asserted (logic low, typically), the oscillator stops and the output enters a high-impedance state. Releasing the pin restarts the output within a few milliseconds — no external enable signal conditioning is needed.

Can DSC1102DI1-050.0000T replace an existing quartz crystal oscillator in my design?

Yes, if the existing oscillator is a 50 MHz LVPECL output in a 6-SMD package. The MEMS-based DSC1102DI1-050.0000T is a drop-in replacement for quartz XOs with the same footprint and supply voltage range (2.25V–3.6V). No external load capacitors are needed — the MEMS resonator is self-contained. Verify the pinout matches your layout; the DSC1102 series uses a standard 6-pin assignment.
