5V41236PGGI

Overview

The 5V41236PGGI is a PCIe Gen2/Gen3 compliant clock generator 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 provides selectable output frequencies of 100 MHz or 200 MHz. Key electrical parameters include a maximum output frequency of 200 MHz, a maximum input frequency of 25 MHz, and a supply voltage of 3.3 V. It exhibits cycle-to-cycle jitter of less than 100 ps and output-to-output skew of less than 50 ps. The component is housed in a 20-pin TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Four differential HCSL outputs for driving multiple devices
• Spread-spectrum capability via pin selection to minimize EMI
• Cycle-to-cycle jitter specification under 100 ps
• PCIe Gen2 phase jitter <3.0ps rms and Gen3 phase jitter <1.0ps rms

Applications

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

Procurement Notes

Verify the specific package variant, as the 5V41236 family includes both TSSOP-20 and VFQFPN options. Confirm that the application requires the 25 MHz input frequency and 100/200 MHz output frequencies supported by this part number. Ensure compatibility with the 3.3 V supply voltage and industrial temperature range specifications before procurement.

Selection Notes

Select the 5V41236PGGI when four differential HCSL outputs are required for PCIe Gen2/Gen3 applications. This model is suitable for designs prioritizing EMI reduction through hardware-selectable spread spectrum without software configuration. Compare against the 5V41235 if only two outputs are needed, or consider the obsolete 5V41236NLGI if a different package footprint was previously used.

Part Context

The 5V41236PGGI belongs to the 5V41236 series of clock synthesizers designed for high-speed serial interfaces. It serves as a direct replacement for older variants like the 5V41236NLGI, which has reached end-of-life status. The PGGI suffix denotes the 20-pin TSSOP package, distinguishing it from other package options within the same functional family.

Replacement Considerations

The 5V41236NLGI is listed as an obsolete alternative with a similar function but a different 20-VFQFPN package. Verify board layout compatibility when substituting between TSSOP and QFN packages.
