Product details

155.52 MHz LVPECL clock source with MEMS reliability

The DSC1122AI5-155.5200 is a MEMS-based XO (Standard) delivering a 155.52 MHz LVPECL output — a common frequency for 10GbE and SONET/SDH line cards. Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an extra regulator.

Enable/Disable function and power budget

The 6-SMD no-lead exposed pad package (7.00mm x 5.00mm, 0.90mm seated height) keeps the thermal path short; the exposed pad should be soldered to a ground plane for best heat transfer.

Active production — no last-time-buy risk

Microchip lists the DSC1122AI5-155.5200 as Active.

Frequently asked questions

What is the datasheet of DSC1122AI5-155.5200?

Engineers need the datasheet to verify electrical specifications, pinout, and timing for design-in.

Where to buy DSC1122AI5-155.5200?

Buyers need immediate purchasing options with stock and lead time to avoid production delays.

Is DSC1122AI5-155.5200 in stock?

Stock availability directly impacts procurement decisions; out-of-stock parts may require alternative sourcing.

What is the price of DSC1122AI5-155.5200?

Pricing influences BOM cost calculations and distributor selection for volume orders.

Does DSC1122AI5-155.5200 have an equivalent part from SiTime?

Engineers often cross-reference MEMS oscillators for second-source or cost optimization.

Is DSC1122AI5-155.5200 RoHS compliant?

Compliance with RoHS is mandatory for many industries; missing info can block procurement.
