PI6CG33601CZLAIEX

Clock Generators, PLLs, Frequency Synthesizers Overview

The PI6CG33601CZLAIEX is a 3.3V very low power PCIe clock generator featuring six differential HCSL outputs with on-chip termination. It accepts a 25 MHz crystal or CMOS input to generate 100 MHz outputs compliant with PCIe Gen1 through Gen6 standards. The device integrates a PLL for very-low jitter performance, including cycle-to-cycle jitter under 50 ps and integrated phase jitter as low as 0.04 ps RMS for PCIe 6.0. Configuration is managed via SMBus or strapping pins, allowing programmable slew rates, output amplitudes, and selectable spread-spectrum options of 0%, -0.25%, or -0.5%. It operates within a temperature range of -40°C to +85°C in a 40-lead 5x5mm TQFN package.
