1.8432 MHz MEMS XO — obsolete, sourced through surplus
3.3 V CMOS output at 1.8432 MHz — ±50 ppm stability
Fixed 1.8432 MHz frequency with CMOS output — a common clock for UART baud-rate generation or legacy microcontroller timing trees. The ±50 ppm frequency stability over -40°C to 85°C keeps the bit-error rate within spec for a 115200 baud UART link across the full temperature range. Supply voltage is 3.3 V, drawing 3 mA typ during operation and 1 µA in standby (power-down) mode — the standby function lets the oscillator shut down with the rest of the clock tree when the system sleeps.
Housed in a 4-SMD no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm.
