The DSC1123AI5-156.2500T is a MEMS-based XO (Standard) from Microchip Technology delivering a 156.25 MHz LVDS output — a common reference for 10 Gigabit Ethernet, PCIe Gen 3, and high-speed SerDes transceivers.
Housed in a 7.00 mm x 5.00 mm 6-SMD package with no lead exposed pad — the 0.90 mm seated height fits tight mezzanine stacks.
Buyers need immediate sourcing channels and current inventory to avoid project delays.
Engineers need full electrical specs, pinout, and timing diagrams to validate fit.
Volume pricing affects BOM cost; sourcing buyers compare distributors for best total cost.
Compliance with RoHS is mandatory for most designs and supply chains.
Design engineers must ensure LVDS output matches receiver input requirements.
Power management and testability depend on output control; drop-in replacement compatibility requires this feature.
