The PLL520-38/-39 is a low phase noise VCXO integrated circuit designed for pulling high frequency fundamental crystals from 65MHz to 130MHz. It features low injection power, PECL or LVDS output, integrated variable capacitors, and supports 2.5V or 3.3V power supply. It is ideal for applications with demanding timing requirements.
The PLL520‑38/39 family are low‑phase‑noise voltage‑controlled crystal oscillators (VCXOs) designed for fundamental crystals from 65 MHz to 130 MHz. They offer selectable PECL (PLL520‑38) or LVDS (PLL520‑39) outputs and operate from 2.5 V or 3.3 V supplies.
The document lists detailed pin functions, absolute maximum ratings, crystal and jitter specifications, as well as LVDS and PECL electrical characteristics. Package options include a 16‑pin TSSOP or a 3 × 3 mm QFN, and ordering information is provided for commercial and industrial temperature grades.
