2309A-1HPGG8

Overview

The Renesas Electronics Corporation 2309A-1HPGG8 is a high-speed phase-lock loop (PLL) clock buffer designed for zero-delay clock distribution. Operating at 3.3V, it accepts one reference input and drives two banks of outputs with low skew characteristics. The device features an on-chip PLL that locks to the input clock via the REF pin, achieving zero delay by aligning the output phase with the incoming signal. It supports operating frequencies from 10 MHz to 133 MHz. The -1H variant provides higher drive capability compared to standard versions. In the absence of an input clock, the device enters a power-down mode with tri-stated outputs.

Feature Summary

• Zero-delay operation using internal PLL to align output phase with input clock
• Low output skew less than 250 ps and cycle-to-cycle jitter under 200 ps
• High drive capability (-1H version) supporting frequencies up to 133 MHz
• Dual output bank configuration: one bank of five and one bank of four outputs

Applications

• High-speed clock distribution in digital systems
• Phase-locked loop clock generation and buffering
• Systems requiring precise clock alignment with minimal skew

Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation to confirm package type and reel quantity specifications. Ensure compatibility with 3.3V supply requirements and check for any recent product change notices affecting assembly or materials.

Selection Notes

Select this component when zero-delay clock buffering is required with low skew performance. The -1H designation indicates enhanced drive strength suitable for higher frequency operations up to 133 MHz. Confirm that the TSSOP-16 package fits the board layout constraints and that the 3.3V voltage range matches the system design.

Part Context

The 2309A series belongs to Renesas' family of zero-delay clock buffers. The 2309A is a 16-pin version derived from the 2305A, offering expanded output capabilities. It integrates an on-chip PLL to eliminate external feedback components, simplifying the design for high-speed clock distribution applications.

Replacement Considerations

Check for direct substitutes within the 2309A family or compatible zero-delay buffers from Renesas. Verify electrical parameters such as voltage, frequency range, and package dimensions before substitution.
