SiT3809
80 MHz to 220 MHz MEMS VCXO
Features
Any frequency between 80.000001 MHz and 220 MHz with 6 decimal places of accuracy
100% pin-to-pin drop-in replacement to quartz-based VCXO Frequency stability as tight as ±10 ppm Widest pull range options from ±25 ppm to ±1600 ppm Industrial or extended commercial temperature range Superior pull range linearity of ≤1%, 10 times better than quartz LVCMOS/LVTTL compatible output Four industry-standard packages: 2.5 mm x 2.0 mm (4-pin),
3.2 mm x 2.5mm (4-pin), 5.0 mm x 3.2 mm (6-pin), 7.0 mm x 5.0 mm (6-pin) Instant samples with Time Machine II and field programmable oscillators RoHS and REACH compliant, Pb-free, Halogen-free and Antimony-free
