The DSC1001CI2-006.1400T is a 6.14 MHz MEMS-based oscillator (XO) producing a CMOS output. The 1.8V to 3.3V supply range lets it share a rail with the MCU or transceiver without a dedicated LDO.
Standby power-down and package footprint
The 4-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. This is a standard 3.2 x 2.5 mm oscillator footprint, so it drops onto the same PCB land pattern as many quartz oscillators of the same size — no layout change needed if the BOM switches from a quartz part to this MEMS device.
