The DSC1001BI1-054.0000: The MEMS resonator eliminates quartz crystal aging drift over the vehicle lifetime.
54 MHz fixed frequency with ±50 ppm stability
Outputs a 54 MHz CMOS clock — a common frequency for 100BASE-TX Ethernet PHYs, CAN-FD controllers, and high-end MCU clock inputs. The ±50 ppm total frequency stability includes initial tolerance, temperature drift, and supply variation; sufficient for most digital logic and serial links without external trimming. Supply voltage range is 1.8V to 3.3V — single rail covers 1.8V, 2.5V, and 3.3V logic families without a separate regulator.
Standby function for power-sensitive modules
Useful for battery-backed ECUs or telematics units that must wake on a CAN or LIN message — the oscillator restarts within the datasheet's startup time.
4-SMD no-lead package — board layout note
Housed in a 5.00 mm × 3.20 mm 4-SMD no-lead package, seated height 0.90 mm max. The land pattern matches standard 4-pin oscillator footprints; no via-in-pad required. Surface-mount reflow profile per JEDEC J-STD-020.
