MEMS clock source at 26 MHz, 3.3 V CMOS
The DSC1033CC1-026.0000T is a 26 MHz MEMS-based XO from the DSC1033 PureSilicon series, delivering a CMOS output at 3.3 V with ±50 ppm frequency stability. The MEMS resonator eliminates the quartz crystal start-up and aging concerns — the oscillator is factory-trimmed and ready at power-on without a load capacitor pair on the board.
Standby function and supply current
Active supply current is 3 mA typical; the standby (power-down) function drops the draw to 1 µA maximum, which keeps the clock tree alive on a backup coin cell or supercap during system sleep.
The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a 0.90 mm seated height, fitting standard reflow profiles and occupying the same footprint as a quartz SMD oscillator.
