Product details

400 MHz LVDS clock source for high-speed timing

The DSC1103DI2-400.0000T is a 400 MHz XO (Standard) with LVDS output, built on a MEMS resonator — no quartz crystal inside. The LVDS signalling keeps jitter low and common-mode noise rejection high over twisted-pair or differential PCB traces, which is why this part lands in SERDES reference clocks, FPGA transceiver banks, and 10G Ethernet PHY timing.

Supply range and standby for system power budgeting

The supply voltage spans 2.25V to 3.63V, covering common 2.5V and 3.3V rails without an external LDO.

Frequently asked questions

What supply voltage does DSC1103DI2-400.0000T require?

It operates from 2.25V to 3.63V, so it can run directly on 2.5V or 3.3V rails without an extra regulator. The 32 mA max active current and 95 µA standby current fit typical FPGA and PHY power budgets.

What is the closest pin-compatible alternative in the DSC1103 family?

Within the DSC1103 series, the base product number DSC1103 covers multiple frequency and stability options in the same 6-SMD, no-lead package. A different frequency variant (e.g., 125 MHz, 200 MHz) shares the same footprint and supply range, but the output type must match — this part uses LVDS, so a replacement must also be LVDS.
