Product details

125 MHz LVPECL timing source with MEMS reliability

The LVPECL output delivers the fast edge rates and low jitter needed for clocking high-speed SERDES, Ethernet PHYs, and FPGA reference inputs. Supply voltage spans 2.25V to 3.6V, so the same BOM line works across 2.5V and 3.3V rails without a separate regulator or level translator.

Microchip lists the DSC1102BI2-125.0000 as Active. The 6-SMD, No Lead package (5.00mm x 3.20mm, 0.90mm seated height) is a standard MEMS oscillator footprint shared across the DSC1102 family. The same PCB land pattern can accept other DSC1102 frequency variants if the BOM needs a last-minute clock change.

58 mA max supply current — budget the rail

The oscillator draws 58 mA max during active operation. In a multi-oscillator design — say, one for the FPGA reference and another for the transceiver — sum the draws; a single LDO feeding both should be sized for 116 mA plus margin.

Frequently asked questions

Where can I buy DSC1102BI2-125.0000 and what is the lead time?

The DSC1102BI2-125.0000 is an active Microchip part sourced through independent distribution.

Is DSC1102BI2-125.0000 RoHS compliant?

The part is listed as RoHS compliant in the Microchip DSC1102 series documentation. The 6-SMD no-lead package uses lead-free terminations. No separate RoHS certificate is held on file; confirm with the datasheet or your compliance team for the specific date-code lot.

What is the closest pin-compatible alternative to DSC1102BI2-125.0000?

Within the DSC1102 series, other frequency variants share the same 6-SMD footprint and supply voltage range. For a different output type (e.g., LVDS or HCSL), the DSC1122 series uses the same package but a different output buffer — verify pin compatibility against the Microchip datasheet before substituting.

Does DSC1102BI2-125.0000 have a standby power down feature?

Yes. The function is Standby (Power Down). When the enable pin is driven low, the output is disabled and supply current drops to 95 µA max. This allows the system to cut clock power during sleep modes.

Is DSC1102BI2-125.0000 compatible with 3.3V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so 3.3V is within the operating window. The LVPECL output levels are referenced to the supply rail — at 3.3V the swing is about 800 mV peak-to-peak, meeting the input threshold of most 3.3V LVPECL receivers.
