Obsolete — sourcing reality for this MEMS oscillator
The DSC6023CI2A-00A4: No pin-compatible direct replacement from Microchip is documented.
What the dual-output MEMS XO delivers
Output is CMOS, so it interfaces directly with most MCU, FPGA, and logic clock inputs without needing a level translator.
Frequency stability and temperature grade
For a 20 MHz carrier, ±25 ppm translates to ±500 Hz of maximum frequency deviation — tight enough for most UART, SPI, and general-purpose clocking applications, though not sufficient for precision timing or Ethernet PHY reference clocks that typically require ±50 ppm or better.
Board-fit and footprint
The low-profile, small-footprint package suits space-constrained PCBs in portable or embedded systems. The part ships in tube packaging.
