8798_AA's Vectron 05/30/02 3:11 PM Page 34 Voltage Controlled Saw Oscillators (VCSO's) VS-550 Description The VS-550 is a dual output (selectable output) SAW based voltage controlled oscillator that operates at the fundamental frequencies of the internal SAW filters. These SAW filters are high-Q quartz devices that enable the circuit to achieve low phase jitter performance over a wide operating temperature range. The dual oscillator is housed in a hermetically sealed J-lead surface mount package offered on tape and reel. It has a frequency select to function that enables either "Frequency 1" or "Frequency 2". 3 Q E L Features AB L I A V A Y R A N I M I PREL * * * * * * * Frequency Select Feature (dual frequency capability) Industry Standard Package, 14 x 9 x 3.5 mm Output Frequencies from 622.080 MHz to 800 MHz 3.3 V Operation Low Jitter < 1 ps rms (50 kHz to 80 MHz offset range) LVPECL Logic Levels with Fast Transition Times Complementary Outputs Performance Characteristics Parameter Symbol Minimum Frequency Center Frequency Absolute Pull Range Linearity Gain Transfer Temperature Stability fo APR Lin KV FSTAB 622.08 50 VCC ICC 2.97 VCC-1.5 500 Supply Voltage Current (No Load) Outputs Mid Level Swing Current Rise Time Fall Time Symmetry Harmonic Spurious Suppression Jitter Zc BW Operating Temperature TOP Maximum Units Notes 800 MHz ppm % ppm/V ppm 1,2,3 1,2,3 2,4 2 2,6 3.3 55 3.63 70 V mA 2,3 2,3 VCC-1.3 650 VCC-1.1 800 20 400 400 55 V mV-pp mA ps ps % dBc ps-rms 2,3 2,3 2,3 2,3,5 2,3,5 2,3 6 6,7 100 k 6 500 kHz 6 C 1,3 3 +430 100 250 250 45 50 OJ Control Voltage Input Impedance Modulation Bandwidth Package Size 1. 2. 3. 4. 5. 6. 7.

Parameters are tested at ambient temperature with test limits guardbanded for specified operating temperature. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310. Measured from 20% to 80% of a full output swing. Not tested in production, guaranteed by design, verified at qualification. Integrated across 50 kHz to 80 MHz, per OC-192.
