The DSC1001CL2-005.6450 is a standard XO (Standard) MEMS oscillator delivering a 5.645 MHz CMOS output from a 1.8V to 3.3V supply rail.
The 1.8V–3.3V supply range lets it run from a 3.3V I/O bank or a lower-voltage core rail without a separate level translator.
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts in automotive ECUs or portable instrumentation.
Yes, the part carries AEC-Q100 ratings, meaning it has passed automotive-grade reliability stress tests and PPAP requirements. It is suitable for under-hood, chassis, and cabin applications where the ambient temperature stays within -40°C to 105°C.
Yes, the function is listed as Standby (Power Down). When the output is disabled, the maximum supply current drops to 15 µA, allowing the oscillator to be gated off during system sleep states.
The output is CMOS, which is a single-ended rail-to-rail logic level compatible with most MCU and FPGA clock inputs. No external termination or level shifting is needed when the supply voltage matches the receiving logic rail.
The base product number DSC1001 covers a range of frequencies and stability grades. A pin-compatible alternative would be another DSC1001 variant with the same 4-SMD no-lead package, supply range, and AEC-Q100 rating but a different frequency or stability. Confirm the exact frequency and stability requirement before substituting.
