PI6LC4820ZDEX

The PI6LC4820ZDEX from Diodes Incorporated is a HiFlex Ethernet Network Clock Generator. This integrated circuit is built around an LC VCO for low phase noise designs, making it suitable for 10GbE applications. It operates with a 3.3V supply voltage and accepts a 25 MHz crystal input or differential inputs at 25 MHz and 156.25 MHz.

This clock generator supports multiple output frequencies including 312.5 MHz, 156.25 MHz, and 125 MHz, configurable via programmable dividers. It features 9 selectable LVPECL or LVDS outputs. The device boasts low phase noise, with a maximum integrated phase noise of 1 ps (12 kHz to 20 MHz), and offers good power supply noise rejection of -50 dBc typical at 156.25 MHz.

The PI6LC4820ZDEX is available in a 48-lead 7x7mm TQFN package, designed for surface mounting. It includes features like a PLL bypass mode for testing and an optional crystal or clock input selection. The device is intended for applications requiring precise clock generation for high-speed networking.

Key electrical specifications include a wide operating voltage range of 3V to 3.6V and an operating temperature range of -40°C to 85°C. The part number PI6LC4820ZDEX-ND is associated with this component.
