Active production, dual-frequency MEMS XO
The DSC6021JI2B-01VE: It delivers two independent output clocks — 21 MHz and 47 MHz — from a single 4-VLGA package, reducing the oscillator count on a board that needs both frequencies.
Typical current draw is 1.3 mA max, making it viable for battery-powered or thermally constrained designs where every milliamp counts.
MEMS vs quartz — the deployment context
The MEMS base resonator gives this XO a shock and vibration tolerance that standard quartz crystals cannot match — relevant for portable equipment, industrial machinery with rotating assemblies, or any enclosure that sees frequent handling or transport.
