5V41235PGG8

Overview

The Renesas 5V41235PGG8 is a PCIe Gen2/Gen3 compliant clock generator featuring spread spectrum capability to reduce electromagnetic interference. It operates with a single supply voltage of 3.135V to 3.465V and delivers two differential HCSL output pairs. The device supports fixed output frequencies of 25MHz, 100MHz, 125MHz, and 200MHz, selectable via hardware pins without software configuration. It utilizes an internal PLL and accepts crystal or clock inputs, housed in a 16-TSSOP package.

Feature Summary

• PCIe Gen2/Gen3 compliant spread spectrum clock generation
• Two differential HCSL output pairs with LVDS termination option
• Hardware-selectable output frequencies: 25MHz, 100MHz, 125MHz, 200MHz
• Cycle-to-cycle jitter < 100 ps; Output-to-output skew < 50 ps

Applications

• PCI Express (PCIe) Gen2 and Gen3 systems
• Ethernet applications requiring 25MHz, 125MHz, or 200MHz clocks
• Embedded communication systems requiring EMI reduction

Procurement Notes

Verify the suffix 'GG8' corresponds to the TSSOP-16 package and tape-and-reel packaging format. Confirm the operating temperature range matches the industrial specification if required for the specific application environment. Ensure input source compatibility with the device's crystal or clock input requirements.

Selection Notes

Select this component when a low-pin-count solution for PCIe clocking is required. The 5V41235 provides fixed frequencies via pin selection, eliminating the need for I2C configuration logic. Verify that the target system requires differential HCSL signaling or can utilize the LVDS termination feature for broader device compatibility.

Part Context

The 5V41235 belongs to the IDT FemtoClock NV family of spread spectrum clock generators. This series is designed for high-performance embedded systems where EMI compliance is critical. The 5V41235 variant specifically targets PCIe interfaces, offering a compact alternative to larger buffer or synthesizer solutions.
