It's a drop-in clock source for any digital logic that needs a clean square wave at that frequency — think MCU clock input, FPGA reference, or a peripheral timing base. The ±50ppm frequency stability is tight enough for UART baud-rate generation and most SPI timing.
Microchip lists the DSC1030BC1-008.0000T as obsolete. That means no further production from the factory — no last-time-buy window remains open. Availability is lot-specific and confirmed at RFQ.
Package and mounting — 4-SMD no-lead
Housed in a 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm. The land pattern is standard for this footprint class — no via-in-pad needed, but the pad geometry should match the recommended layout in the datasheet to keep the solder fillet consistent.
Active current is 3mA typical at 8 MHz.
