Obsolete — sourced through independent channels
The DSC6001HI1A-020.0000T is officially obsolete per Microchip's product status. Confirm availability and pricing at RFQ.
This is a 20 MHz MEMS-based XO (standard oscillator) with CMOS output, rated for -40 to +85 °C industrial temperature range and qualified to AEC-Q100 — suitable for automotive body, cabin, or chassis applications where a quartz crystal would be too shock-sensitive. Frequency stability is ±50 ppm across the full temperature and voltage range, which means the 20 MHz clock stays within 1 kHz of nominal — tight enough for a CAN bus or LIN node without external trimming.
Operates from a single 1.71 V to 3.63 V supply, so it can run directly off a 1.8 V, 2.5 V, or 3.3 V rail without a separate LDO.
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 0.50 mm pitch land pattern is common among MEMS oscillators; the enable/disable function on pin 1 lets the system gate the clock without a separate switch.
