8V43042PGG

Overview

The 8V43042PGG is a FemtoClock III programmable clock generator manufactured by Renesas Electronics Corporation. It supports input frequencies up to 167 MHz and generates output frequencies up to 1.2 GHz. The device operates on a single 3.3 V supply voltage with a maximum operating temperature of +85 °C. It features low jitter performance, typically less than 0.5 ps RMS phase noise, making it suitable for high-speed serial applications. The component is housed in a TSSOP-20 package.

Feature Summary

• FemtoClock III series with ultra-low jitter (<0.5 ps RMS)
• Programmable frequency synthesis up to 1.2 GHz
• Single 3.3 V power supply operation
• Supports spread spectrum clocking (SSC) capabilities

Applications

• High-speed serial link clock generation
• PCI Express and SATA interface timing
• Networking equipment clock distribution
• ASIC and FPGA clock synthesis

Procurement Notes

Verify the specific suffix 'PGG' corresponds to the TSSOP-20 tube packaging configuration as listed in official Renesas documentation. Confirm RoHS compliance status through the current datasheet revision. Check for any recent product change notices (PCN) that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when low jitter performance is critical for high-speed data transmission interfaces. Ensure the design requires a single 3.3 V supply and fits within the TSSOP-20 footprint. Compare against other FemtoClock III variants if different input/output configurations or package sizes are needed.

Part Context

The 8V43042PGG belongs to the FemtoClock III family, designed for applications requiring precise clock generation with minimal phase noise. This series integrates voltage-controlled oscillators (VCXOs) and digital synthesizers to provide flexible clock solutions for demanding digital systems.

Replacement Considerations

Consult Renesas official cross-reference guides for direct replacements. Verify compatibility with existing PCB layout and software configuration tools when substituting with other FemtoClock III models.
