Product Data Sheet J-Type Voltage Controlled Crystal Oscillator Features Output Frequencies from 1.024 MHz to 250.000 MHz +3.3 or +5.0 volt options Small 14mm x 9mm J-type Package CMOS or PECL Outputs Low phase noise and custom options 0/70° C or –40/85° C operating temperature Tri-State output (CMOS) Enable/Disable (PECL) Applications Clock Smoothing Frequency Translation SONET, SDH, ATM, DSLAM, ADM Description The J-type voltage controlled crystal oscillator incorporates VI’s advanced VCXO performance capabilities while adhering to a package footprint compatible with the industry-common J-lead package. The J-type VCXO is a quartz stabilized square wave generator with either a CMOS output for driving CMOS/TTL loads or a PECL output. The device is packaged in a 6 pin J-lead ceramic package and is hermetically sealed with a grounded conductive lid.
