简 介: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.

OUTPUT RANGE DESCRIPTION
DIVIDER FREQUENCY RANGE 10 - 20MHz OUTPUT BUFFER CMOS
PLL502-52
The PLL502-52 is a monolithic low jitter, high performance CMOS VCXO IC Die. 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.
