5V41236PGGI8

Overview

The 5V41236PGGI8 is a PCIe Gen2/3 compliant clock synthesizer manufactured by Renesas Electronics. It features four differential HCSL outputs and supports spread-spectrum capability to reduce electromagnetic interference (EMI). The device operates with a 25 MHz crystal input and generates output frequencies of 100 MHz or 200 MHz. Key electrical parameters include a maximum output frequency of 200 MHz, a cycle-to-cycle jitter of less than 100 ps, and an output-to-output skew of less than 50 ps. It functions within a supply voltage range of 3.3 V and supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Four differential HCSL outputs for driving multiple devices
• Spread-spectrum capability to substantially reduce EMI
• Cycle-to-cycle jitter <100 ps and output-to-output skew <50 ps
• PCIe Gen2 phase jitter <3.0ps RMS and Gen3 phase jitter <1.0ps RMS

Applications

• Communication systems requiring low-jitter clocking
• Embedded systems demanding EMI reduction
• PCI Express Gen2 and Gen3 compliant designs

Procurement Notes

Verify the suffix 'I8' corresponds to the specific tape-and-reel packaging and industrial temperature grade (-40°C to +85°C) required for the application. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the 20-TSSOP package dimensions fit the target PCB layout constraints.

Selection Notes

Select this component when four differential HCSL outputs are necessary for PCIe Gen2/3 applications. The pin-selectable spread spectrum feature eliminates the need for software configuration. Compare against the 5V41235 if only two outputs are sufficient, as it offers similar performance in a smaller 16-pin package.

Part Context

The 5V41236 belongs to the 5V4123x family of PCIe clock synthesizers. It shares architectural similarities with the 5V41235 but provides additional output channels. The 'PGGI8' designation indicates the TSSOP-20 package, industrial temperature rating, and reel packaging format.

Replacement Considerations

The 5V41235 serves as a functional alternative for designs requiring only two differential outputs. Verify pin compatibility and output count requirements before substitution.
