The DSC1103AI1-125.0000 is a MEMS-based XO (Standard) oscillator delivering a 125 MHz LVDS output from a 2.25V to 3.63V supply rail — a single part covers both 2.5V and 3.3V clock domains without a level translator.
Housed in a 7.00mm x 5.00mm 6-SMD package with no-lead exposed pad, the 0.90 mm seated height keeps it low-profile for mezzanine card spacing.
Yes — the DSC1103AI1-125.0000 is footprint- and output-compatible with most 7.0mm x 5.0mm 125 MHz LVDS quartz oscillators. The MEMS resonator has a faster startup time and better shock tolerance, but the pinout (VDD, GND, OUT, /OUT, OE/STBY) follows the industry-standard 6-pad layout. Confirm the supply voltage range (2.25V to 3.63V) and the standby polarity match your existing design.
Yes — the part includes a Standby (Power Down) function. When asserted, the output is disabled and the supply current drops to 95 µA max, versus 32 mA max in active mode. This is useful for power-gating the clock in battery-operated or duty-cycled systems.
