Product details

156.25 MHz LVPECL MEMS oscillator for high-speed clocking

The DSC1122BE1-156.2500T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1122 series, delivering a fixed 156.25 MHz LVPECL output. That frequency is a standard reference for 10GbE, Fibre Channel, and FPGA transceiver banks — the LVPECL swing provides the edge rate and common-mode range that CML and AC-coupled LVPECL receivers expect. That matters in multi-rail designs where the oscillator's draw contributes to the idle power budget.

Microchip lists the DSC1122BE1-156.2500T as Active.

Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The -20 to +70°C operating range covers commercial and most indoor telecom environments.

Frequently asked questions

How can I order the DSC1122BE1-156.2500T or request a quote?

The DSC1122BE1-156.2500T is an active, in-production part from Microchip. No stock-holding claim is made; sourcing is through independent distribution per your volume and delivery window.

What is the output type of the DSC1122BE1-156.2500T?

LVPECL (Low-Voltage Positive Emitter-Coupled Logic). The output swing and common-mode voltage are compatible with standard LVPECL receivers and AC-coupled CML inputs found on most 10GbE PHYs and FPGA transceivers.

Can the DSC1122BE1-156.2500T be used as a replacement for the DSC1122BE1-156.2500?

The base product number DSC1122 indicates the same die and package family. The suffix T denotes Tape & Reel packaging. Functionally, the two order codes share the same oscillator core, output type, and frequency — the difference is packaging format. Confirm the reel quantity and tape orientation match your pick-and-place setup before substituting.
