Lifecycle reality for a MEMS clock source
The DSC6021CI2A-004HT is listed as Obsolete by Microchip Technology. This means the manufacturer has discontinued production and there is no official last-time-buy window remaining through the factory channel. No pin-compatible successor is recorded in the manufacturer's lifecycle data.
Automotive-grade MEMS oscillator with dual outputs
This means it can be placed in under-hood or cabin electronics where the ambient temperature profile and vibration environment exceed commercial-grade limits.
Maximum current draw is 1.3 mA typical — at 3.3 V that is under 4.3 mW, negligible in a power budget that includes a microcontroller or SoC. For a 10 MHz output, this translates to a maximum frequency error of ±250 Hz over temperature — tight enough for a UART baud-rate reference or a CAN node clock without external trimming.
Supplied in Tape & Reel packaging, compatible with automated pick-and-place assembly. The 0.90 mm height keeps it within the profile constraints of a two-layer automotive ECU or a sensor module enclosure.
