PI6CFGL202BLIE

Overview

The PI6CFGL202BLIEX is a low-power PCIe 3.0 compliant clock generator manufactured by Diodes Incorporated. It features an integrated Phase-Locked Loop (PLL) and crystal driver, accepting a 25MHz input from a crystal or single-ended clock source. The device generates two differential output pairs with selectable frequencies of 25MHz, 100MHz, 125MHz, or 200MHz via external pins. Outputs support Low-Power HCSL and LVDS formats, powered by a nominal 1.8V supply (range 1.05V to 3.3V). Key electrical parameters include a typical cycle-to-cycle jitter of 35ps and spread spectrum modulation options of -0.5% or -0.75%. It operates within a temperature range of -40°C to +85°C in a 16-pin TSSOP package.

Feature Summary

• PCIe 3.0/2.0/1.0 and Ethernet compliant spread spectrum clock generation
• Configurable output frequencies: 25MHz, 100MHz, 125MHz, and 200MHz
• Dual differential outputs supporting Low-Power HCSL and LVDS standards
• Spread spectrum selection via pins: No Spread, Down -0.5%, or Down -0.75%

Applications

• PC motherboard system clocks
• Embedded systems requiring EMI reduction
• PCI Express interface timing

Procurement Notes

Verify the ordering suffix 'LIEX' corresponds to the specific 16-pin TSSOP tape and reel packaging configuration. Confirm RoHS compliance status for the specific lot, as the datasheet indicates lead-free and green manufacturing standards. Ensure the application design accounts for the specified 3.3V digital core voltage and the independent 1.05V to 3.3V output supply range.

Selection Notes

Select this component when a single-channel generator with dual differential outputs is required for PCIe or Ethernet applications. Verify that the target frequency (25MHz, 100MHz, 125MHz, or 200MHz) matches the system requirements and can be set via the S0/S1 pins. Ensure the load termination supports either HCSL or LVDS signaling levels, noting the separate VDDO power supply requirement for the output stage.

Part Context

This part belongs to the PI6CFGL series of low-power clock generators designed for high-speed serial interfaces. It integrates the PLL and crystal oscillator components typically found in discrete designs, simplifying the PCB layout for PCIe and Ethernet controllers. The device replaces multiple discrete timing components by providing a complete solution for clock distribution and EMI mitigation.
