Microchip lists the DSC6001HI2A-042.0000 as Obsolete. Do not plan a new design around this order code.
Rated AEC-Q100, this oscillator was qualified for automotive stress and reliability requirements.
Key ratings for clock-tree fit
42 MHz fixed frequency with CMOS output drives MCU clock inputs, Ethernet PHY reference clocks, or FPGA PLLs directly — no external load capacitors needed, unlike a quartz crystal. Frequency stability of ±25 ppm keeps the clock edge within tight timing margins for 100BASE-T or USB full-speed interfaces. Supply voltage spans 1.71 V to 3.63 V, so the same part works on 1.8 V, 2.5 V, or 3.3 V rails without a level translator.
Package and board layout note
Housed in a 4-SMD, No Lead package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm. The small footprint suits space-constrained automotive modules.
