Dual-frequency MEMS oscillator for timing-tree consolidation
The DSC6121CI2A-00AQ: A single oscillator replaces two cans on the BOM — the 12 MHz feeds the MCU core or USB peripheral, while the 24 MHz clocks the Ethernet PHY or FPGA fabric, saving board space and reducing the timing-tree component count.
Obsolete — sourcing through independent channels
A board-spin to a current-production MEMS oscillator from the DSC61XX or DSC8XX family may be the practical migration path for volume builds.
