PI6C557-03AQLEX Description

Short technical summary and product information.

The PI6C557-03AQLEX from Diodes Incorporated is an advanced spread spectrum clock generator compliant with PCI Express 2.0 and Ethernet standards. This device is engineered to significantly reduce Electromagnetic Interference (EMI) in PC and embedded system applications.

 

It features two differential outputs, supporting both HCSL and LVDS signaling. The device operates with a supply voltage of 3.3V ±10% and accepts a 25MHz crystal or clock input. It can generate clock frequencies of 25MHz, 100MHz, 125MHz, and 200MHz. The spread spectrum functionality offers selectable options of -0.5%, -0.75%, or no spread, with a spread bypass option available.

 

Key electrical characteristics include low phase jitter of 2.1ps RMS (typ) and cycle-to-cycle jitter of 35ps (typ). The PI6C557-03AQLEX is housed in a 16-pin TSSOP package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C.

 

This component is AEC-Q 100 qualified, making it suitable for automotive applications requiring specific change control. It is also Totally Lead-Free & Fully RoHS Compliant, Halogen and Antimony Free, designated as a "Green" device.
