The PI6C557-05LEX from Diodes Incorporated is a spread spectrum clock generator designed to meet PCI Express 2.0 and Ethernet requirements, significantly reducing electromagnetic interference (EMI) in PC and embedded systems.
This device utilizes Phase-Locked Loop (PLL) technology to generate four differential outputs at 100MHz and 200MHz clock frequencies from a 25MHz crystal or reference input. It supports spread spectrum options of -0.5%, -1.0%, -1.5%, and no spread, with selection configurable via external pins. The outputs are compatible with LVDS and HCSL standards, operating at 0.7V current mode differential pair.
Key electrical specifications include a supply voltage range of 3.135V to 3.465V (typically 3.3V ±5%). It features low phase jitter of 2.1ps RMS (typical) and cycle-to-cycle jitter of 40ps (typical). The operating temperature range is industrial, from -40°C to 85°C.
The PI6C557-05LEX is supplied in a 20-pin TSSOP package, suitable for surface mounting. It is RoHS3 compliant, lead-free, and halogen/antimony-free, making it a 'Green' device. The product is also rated MSL 1 for moisture sensitivity.
