PLL502-52 Low Phase Noise Divider by 2 VCXO (10MHz to 20MHz) FEATURES • • • • • Integrated voltage-controlled crystal oscillator circuitry (VCXO) (pull range 380ppm minimum). VCXO tuning range: 0V - V DD V. Uses inexpensive fundamental-mode parallel resonant crystals (from 20 to 40MHz). Integrated divider by 2: output range of 10MHz to 20MHz. 2.5V or 3.3V supply voltage. Selectable High Drive (30mA) or Standard Drive (10mA) output. Available in 8-Pin TSSOP or SOIC.

It allows the control of the output frequency with an input voltage (VCON), using a low cost crystal. This makes the PLL502-52 ideal for a wide range of applications requiring a VCXO output in the 10MHz to 20MHz range, using a fundamental crystal ranging from 20 to 40 MHz. ÷2 FREQUENCY RANGE 10 - 20MHz OUTPUT BUFFER CMOS BLOCK DIAGRAM X IN XOUT XTAL OSC V A R IC A P C LK OE VCON 47745 Fremont Blvd., Fremont, California 94538 Tel (510) 492-0990 Fax (510) 492-0991 www.phaselink.com Rev 9/17/04 Page 1 PLL502-52 Low Phase Noise Divider by 2 VCXO (10MHz to 20MHz) PIN DESCRIPTIONS Name Number Type XOUT N/C VCON GND CLK VDD 1 2 3 4 5 6 I I P O P OE 7 I XIN 8 I Description Crystal output.

It is assumed that the crystal will be at nominal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This however may reduce the pull range. PACKAGE INFORMATION 8 PIN ( dimensions in mm ) TSSOP Narrow SOIC Symbol Min. Max. Min. Max.
