Surface Mount
Oven Stabilized Oscillator
DOC Series
OCXO / VCOCXO
Description:
Features:
Connor-Winfield’s high stability DOC series are
exceptionally precise frequency
8
standards, excellent for use
102 F
050
DOC .0 MHz
in cellular base stations, test
10
equipment, Synchronous
Ethernet and VSAT applications.
These true surface mount
OCXO / VCOCXO oscillators
provide frequency stabilities in the range of ±20
ppb to ±250ppb, over the commercial, extended
commercial or the industrial temperature range.
The DOC series is available with a CMOS
output and a Voltage Controlled Option. These
oscillators provide outstanding phase noise
characteristics that will meet the most stringent
requirements.
