VCXO-5030-DCE-H

VX-503 Voltage Controlled Crystal Oscillator VX-503 Description The VX-503 voltage controlled crystal oscillator expands VI’s advanced VCXO performance capabilities while adhering to a package footprint compatible with the industry-common J-lead package. The VX-503 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. Features • • • • Small 14mm x 9mm Low phase noise Frequency Range: 1 MHZ to 800 MHZ Previous Model: J-Type Applications • Clock Smoothing • Frequency Translation • SONET, SDH, ATM, DSLAM, ADM Performance Speci cations Parameter Pin Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Min Typ Max Function Units Condition Pin Out Information for the CMOS output Option Symbol VC Tri-State1 GND Output CMOS/TTL select1,2 VCXO Control Voltage TTL logic low disables output. TTL logic high, or no connect, enables output. Case and Electrical Ground VCXO Output TTL logic low optimizes symmetry for CMOS. TTL logic high, or NC, optimizes symmetry for TTL Power Supply Voltage (5.0 V or 3.3 V ±10%) Pin 6 VCC 1. Standard option. Tri-State can be connected to pin 5 and CMOS/TTL select would be on pin 2. 2. Output is HCMOS. For frequencies >12MHz, this option optimizes symmetry for either CMOS or TTL thresholds. Ground this pin for frequencies < 12MHz.
