The 1.8432 MHz frequency is a common baud-rate generator for UART and serial communication links — a single oscillator serves the clock tree without a PLL multiplier.
Operating from 1.8V to 3.3V, this oscillator spans 1.8V logic, 2.5V I/O, and 3.3V peripheral rails — one BOM line covers multiple voltage domains without a level translator on the clock output.
Housed in a no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the compact footprint suits space-constrained PCBs in automotive camera modules or handheld instruments.
The DSC1001 series is the active baseline; the DI2 suffix denotes the specific frequency, stability grade, and temperature range.
