It allows the control of the output frequency with an input voltage (VCON), using a low cost crystal. The ABV806X is designed to address the demanding requirements of high performance applications such as SONET, GPS, Video, etc. XOUT DNC OE_CTRL VCON 12 13 14 11 DNC 9 8 7 XIN GNDBUF QBAR VDDBUF Q ABV806X 15 16 1 2 3 4 6 5 GNDANA 3x3mm QFN Note1: ^ Denotes internal pull up resistor.

(See OE_CTRL Logic Levels above). Voltage control input. Ground for analog circuitry. Tuning inductor connection. The inductor is recommended to be a high Q small size 0402 or 0603 SMD component, and must be placed between LP and adjacent LM pin. Place inductor as close to the IC as possible to minimize parasitic effects and to maintain inductor Q. GND connection for output buffer circuitry. PECL or LVDS output. VDD connection for output buffer circuitry. VDDBUF should be separately decoupled from other VDDs whenever possible. Complementary PECL, LVDS output. GND connection for output buffer circuitry.

P ERFORMANCE TUNING & INDUCTOR VALUE SELECTION P lease refer to Abracon’s ‘Tuning Assistance’ software to automatically calculate the optimum inductor values for your application. In addition, the chart below could be used as a reference for quick inductor value selection. Please note that the inductor values mentioned in the table below, or when using the ‘Tuning Assistance’ are derived based on the parasitic values of Abracon’s evaluation board. For performance enhancement of your custom board design, please follow the following instruction: Use the special test modes “VCO Max” and “VCO Min” to determine the optimum inductor value. “VCO Max” represents the high end of the VCO range and “VCO Min” represents the low end of the VCO range. The output frequency in the “VCO Max” and “VCO Min” test modes is VCO/16. This means that the output frequencies are around the crystal frequency that will be used. The optimum inductor value is where the target crystal frequency is closest to the middle between the “VCO Max” and “VCO Min” output frequencies. In this case the VCO will lock in the middle of its tuning range with maximum margin on either side. 3 0332 Esperanza., Rancho Santa Margarita, Ca 92688 Ph: 949-546-8000 Fax: 949-546-8001 w ww.Abracon.com 9 /1/05 Page 3 ( Preliminary) A BV8068/69 3 20-640MHz Low Phase Noise VCXO E LECTRICAL SPECIFICATIONS 1 .
