Microchip has marked the DSC1018DI1-028.6360T as Obsolete. Available through independent surplus channels; quantities are lot-specific and confirmed at RFQ.
28.636 MHz MEMS oscillator with standby function
A MEMS-based XO (Standard) delivering a 28.636 MHz CMOS output on a 1.8V supply rail. The standby (power-down) function drops supply current to 1 µA max when the enable pin is pulled low — useful for battery-powered equipment that clocks down between active cycles.
Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm — a compact footprint that matches the common 2.5 x 2.0 mm MEMS oscillator land pattern.
Frequency stability and current draw
Frequency stability is ±50 ppm across the full temperature and voltage range — tight enough for UART baud-rate generation and most MCU clock trees without external trimming. Typical supply current is 3 mA during active oscillation, so the oscillator load on a 1.8V rail is negligible in a mixed-signal power budget.
