FEATURES

• 65MHz to 130MHz Fundamental Mode Crystal.

• Output range: 65MHz – 130MHz (no PLL).

• Low Injection Power for crystal 50uW.

• PECL (PLL520-38) or LVDS output (PLL520-39).

• Integrated variable capacitors.

• Supports 2.5V or 3.3V-Power Supply.

• Available in 16-Pin (TSSOP or 3x3 QFN).

DESCRIPTION

The PLL520-38/-39 is a family of VCXO IC’s

specifically designed to pull high frequency

fundamental crystals from 65MHz to 130MHz, with

selectable PECL or LVDS outputs.. They achieve

very low current into the crystal resulting in better

overall stability. Their internal varicaps allow an on

chip frequency pulling, controlled by the VCON

input. Their very low jitter makes them ideal for the

most demanding timing requirements.
