MEMS oscillator for 156.25 MHz clock trees
The DSC1103CE1-156.2500T is a MEMS-based XO (standard oscillator) delivering a 156.25 MHz LVDS output — a common reference frequency for 10/25/40 GbE SerDes, PCIe Gen 3/4, and FPGA transceiver banks.
Wide supply and standby for mixed-voltage boards
Supply voltage spans 2.25 V to 3.63 V, covering both 2.5 V and 3.3 V logic rails without an external regulator.
Commercial temperature grade and 6-SMD footprint
The 3.20 mm x 2.50 mm 6-SMD no-lead package fits a standard 2.5 x 3.2 mm oscillator footprint; the 0.90 mm seated height suits tight mezzanine or blade-slot clearances.
Active lifecycle — no end-of-life signal
The MEMS supply chain is generally less constrained than quartz — typical lead times run shorter, though firm confirmation requires an RFQ against the specific BOM quantity.
