Obsolete — last-time-buy reality
The DSC6121JI2A-00AH is marked obsolete by Microchip Technology. No official successor or second-source is listed in the product record. A board spin is required for any functional replacement.
Dual-output clock — 50 MHz and 100 MHz from one package
The dual-output architecture saves a second oscillator footprint and routing layer on dense PCBs — useful when a processor core clock and a peripheral bus clock must run from synchronized references.
±25 ppm stability across industrial temperature
This covers most industrial Ethernet, CAN, and USB timing budgets without external temperature compensation. Typical supply current is 3 mA max, keeping the thermal load low in the VLGA package.
MEMS resonator — no quartz, no crystal aging drift
The oscillator is factory-trimmed and ready to place. The 4-VLGA package (0.50 mm pitch, exposed pad) reflows on a standard lead-free profile.
