5V41235PGG

Overview

The Renesas 5V41235PGG is a PCIe Gen2/3 compliant spread spectrum clock generator housed in a 16-TSSOP package. It features two differential HCSL outputs and operates on a 3.3V supply (3.135V to 3.465V). The device supports input frequencies via clock or crystal sources, with a maximum output frequency of 200MHz. Designed for communication and embedded systems, it reduces electromagnetic interference through selectable spread amounts and output frequencies controlled by select pins.

Feature Summary

• PCIe Gen2/3 Compliant: Supports spread spectrum capabilities for EMI reduction.
• Dual Differential Outputs: Provides two HCSL differential clock signals.
• Spread Spectrum Control: Spread amount and output frequency are selectable via hardware select pins.
• Standard Packaging: Available in a 16-TSSOP surface-mount package.

Applications

• PCI Express (PCIe) Gen2 and Gen3 system designs
• Communication equipment requiring low EMI clocking
• Embedded systems utilizing 25 MHz, 125 MHz, or 200 MHz outputs

Procurement Notes

Verify the specific suffix against the datasheet to confirm package type and temperature range. The 'GG' suffix typically denotes a tube carrier, while 'G8' indicates tape and reel. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) requirements for your assembly process before ordering.

Selection Notes

Select this component when a single PLL-based solution is needed for PCIe applications requiring spread spectrum functionality. Ensure the design utilizes differential HCSL receivers compatible with the output swing. Verify that the required output frequencies (25MHz, 125MHz, 200MHz) align with the pin-selectable options provided by the device architecture.

Part Context

This part belongs to the IDT/Renesas 5V41235 family of PCIe synthesizers. It serves as a direct replacement for legacy IDT parts with similar specifications. The device is distinct from buffer-only solutions like the 5PB series, as it includes an integrated PLL for frequency synthesis from a reference input.

Replacement Considerations

The 5V41235PGGI is a variant with an industrial temperature range (-40°C to +85°C), whereas the PGG is commercial grade (0°C to 70°C). Check if the extended temperature range is required for the application environment.
