Product details

156.25 MHz LVPECL MEMS oscillator – active production

The DSC1102BE1-156.2500T is a MEMS-based XO (Standard) from Microchip's DSC1102 series, delivering a 156.25 MHz LVPECL output — the standard reference frequency for 10GbE, Fibre Channel, and many SerDes PLLs. The LVPECL differential pair drives long PCB traces with controlled edge rates; expect a 100-ohm differential termination at the receiver.

Supply range, standby, and temperature grade

Operates from 2.25V to 3.6V — covers both 2.5V and 3.3V rails without an extra regulator. This is the commercial temperature band — fine for indoor networking gear, base stations, and test equipment.

6-SMD no-lead package, 5.00mm x 3.20mm footprint, seated height 0.90mm max. Standard reflow profile for lead-free assembly.

Frequently asked questions

What is the output type of DSC1102BE1-156.2500T?

LVPECL (Low-Voltage Positive Emitter-Coupled Logic) — a differential output that requires a 100-ohm termination at the receiver for proper signal levels.

Does DSC1102BE1-156.2500T support a standby function?

Yes. The standby (power down) function disables the output and reduces supply current to 95 µA max, allowing the oscillator to be gated for system sleep modes.
