The DSC1121 is a silicon MEMS based CMOS
oscillator offering excellent jitter and stability
performance over a wide range of supply
voltages
temperature grades from Commercial (0ºC to
70ºC) to Automotive (-55ºC to 125ºC), The
DSC1121
increments of 100Hz (up to four decimal point
resolution) with supply voltages between 2.5V
to 3.3 Volts.
Available in industry standard 7X5mm, 5X3.2
and 3.2X2.5mm packages, the DSC1121 is a
“drop-in” replacement for a standard 4 pin
quartz oscillator.
