Dual-frequency MEMS XO — 12 MHz and 24 MHz on one die
The DSC6121JI3B-01VGT: That means one BOM line covers two clock domains, reducing part count on the board.
Industrial temperature range and low power budget
Frequency stability is ±20 ppm, tight enough for most serial data links (UART, SPI, I2C) without external trimming. Maximum supply current is 3 mA typical — the MEMS resonator draws significantly less than a quartz crystal oscillator at the same frequency, so it fits battery-powered or thermally constrained designs where every milliamp counts.
