2309A-1HPGG

Overview

The Renesas Electronics Corporation 2309A-1HPGG is a high-speed phase-lock loop (PLL) clock buffer designed for zero delay clock distribution. Operating at 3.3V, it accepts one LVCMOS reference input and drives nine low skew outputs across two banks. The device supports frequencies from 10 MHz to 133 MHz with cycle-to-cycle jitter under 200 ps and output skew less than 250 ps. It is housed in a 16-pin TSSOP package with dimensions of 5.0 x 4.4 x 1.0 mm and a 0.65 mm pitch.

Feature Summary

• Zero delay operation aligns input and output phases using an on-chip PLL.
• High drive capability (-1H version) ensures faster rise and fall times.
• Low jitter performance with cycle-to-cycle jitter below 200 ps.
• Outputs tri-state automatically when no input clock is present.

Applications

• High-speed clock distribution networks
• System synchronization in digital logic circuits
• Buffering reference clocks for multiple downstream components

Procurement Notes

Verify the specific suffix 'PGG' against official Renesas documentation to confirm the exact package variant and environmental compliance status. Ensure the operating temperature range matches the system requirements, as commercial variants are specified for 0°C to 70°C while industrial versions support -40°C to 85°C.

Selection Notes

Select this component for applications requiring precise phase alignment between source and destination clocks without external timing adjustments. The -1H designation indicates higher drive strength compared to standard versions, suitable for driving heavier loads or longer traces within the 133 MHz frequency limit.

Part Context

This part belongs to the IDT 2309 family of zero delay buffers, originally developed by Integrated Circuit Systems (ICS) and now manufactured by Renesas. It serves as a 16-pin solution derived from the 2305A architecture, specifically optimized for distributing a single clock signal to multiple synchronized destinations with minimal skew.

Replacement Considerations

Direct substitutes include other zero delay buffers from the same family, such as the 2309A-1D or 2309-1HDCG, provided the package type (SOIC vs. TSSOP) and electrical characteristics meet the design constraints.
