PI6LC4833ZBIE

Overview

The PI6LC4833ZBIE is a clock generator designed for PowerPC network processors, utilizing LC VCO technology. It generates CPU core/PCI clocks, PCIe Gen1/2 clocks, SRIO, and Gigabit Ethernet MAC/PHY clocks from a 25MHz crystal or differential input. The device features four HCSL outputs (100/125/200/250MHz), two LVCMOS outputs (33/50/66/100MHz), five LVCMOS outputs (25/125MHz), one LVPECL output (312.5/156.25/125MHz), one CMOS output (156.25/125MHz), and one LVPECL output (125/25MHz). It operates at 2.5V or 3.3V with typical RMS integrated phase noise of 0.5ps at 3.3V and 1.0ps at 2.5V.

Feature Summary

• Supports 2.5V and 3.3V supply voltages with low jitter performance.
• Generates multiple clock types including HCSL, LVCMOS, LVPECL, and CMOS.
• Includes PLL bypass mode for testing purposes.
