ECS-VX0-97
SMD VOLTAGE CONTROLLED CRYSTAL OSCILLATOR
The ECS-VXO-97 offers the frequency control
of a VCXO in a SMD, ceramic package.
Frequency can be pulled up to ± 100 ppm by
varying the control voltage of 2.5V by up to
±2.0V.
FEATURES
• 2.0 mm low profile
• Waveform symmetry of 40/60%
• SMD version
• 3.3V operation (optional)
• Tape & Reel (1000 pcs)
• PbFree/RoHS Compliant
