MEMS clock generator with four independent LVCMOS lanes
The DSC400-0111Q0087KE2T is a MEMS-based XO (Standard) that replaces up to four discrete crystal oscillators with a single 20-VFQFN package — three output frequencies are factory-programmed: 25 MHz, 24 MHz, and 33.333333 MHz, all delivered as LVCMOS signals.
Supply voltage tolerance and frequency stability
Rated for 2.25 V to 3.6 V supply, the part spans both 2.5 V and 3.3 V logic rails without an intermediate regulator — a single rail can feed the oscillator and the downstream FPGA or PHY. Frequency stability is ±25 ppm over the -20 to +70 °C commercial temperature range — tight enough for 100BASE-T Ethernet and USB 2.0 without a separate TCXO.
