Dual-frequency MEMS XO — 45.1584 MHz and 49.152 MHz
The DSC2010FI2-B0009T is a MEMS-based XO that outputs two fixed frequencies: 45.1584 MHz and 49.152 MHz, both on a single device.
Operates from 2.25 V to 3.6 V, covering the common 2.5 V and 3.3 V logic rails. The LVCMOS output sinks or sources up to 35 mA max — enough to drive a single load with a short trace; for multiple fan-outs, buffer the output.
Package and footprint — 14-VFQFN with exposed pad
Housed in a 14-lead VFQFN with exposed pad, 3.20 mm x 2.50 mm body, 0.90 mm max height.
No pin-compatible second source or official successor is cited.
