PLL502-51 Low Phase Noise VCXO (20MHz to 52MHz) 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 52MHz). 2.5V or 3.3V supply voltage. Selectable High Drive (30mA) or Standard Drive (10mA) CMOS output. Available in 8-Pin SOIC or TSSOP. DESCRIPTION XOUT 1 N/C 2 VCON 3 GND 4 PLL502-51 • • PIN CONFIGURATION 8 XIN 7 OE^ 6 VDD 5 CLK Note: ^ denotes internal pull up OUTPUT RANGE The PLL502-51 is a monolithic low jitter, high performance CMOS VCXO IC. It allows control of the output frequency with an input voltage (VCON), using a low cost crystal. This makes the PLL502-51 ideal for a wide range of applications from 20MHz to 52MHz (including 27MHz, 35.328MHz, etc.).
