Suitable for base stations (Femtocell) requiring high stability
Output HCMOS or clipped sine wave available
Exceptionally good value for close-to OCXO performance
Low power use, 4mA for HCMOS, 2.4mA max for clipped sine
Lower phase noise available by external capacitor
10.0MHz to 52.0MHz
XOVN-9000B - OUTLINES AND DIMENSIONS
DESCRIPTION
XOVN-9000B series VCXOs are ceramic SMD VCXOs packaged in an
the industry-standard, ultra-miniature 3.2 x 2.5mm package. This
VCXO exhibits exceptionally high frequency stability performance and
provides cost-effective high performance, comparable to OCXO.
