2309A-1HDCG

Overview

The Renesas 2309A-1HDCG is a high-speed, phase-lock loop (PLL) based clock buffer designed for zero-delay clock distribution. It accepts one reference input and drives two banks of outputs, specifically configured as five outputs in one bank and four in another. Operating at 3.3V with an input frequency range of 10MHz to 133MHz, the device achieves output skew of less than 250ps and cycle-to-cycle jitter below 200ps. The -1H variant provides higher drive strength with faster rise and fall times compared to standard versions. It features on-chip PLL feedback obtained from the CLKOUT pad and operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Zero-delay buffer architecture aligning input and output clock phases via internal PLL
• 1:9 fan-out configuration distributing one input to nine LVCMOS outputs
• High drive capability (-1H version) supporting frequencies up to 133MHz
• Low jitter performance with <200 ps cycle-to-cycle specification

Applications

• High-speed clock distribution networks
• System synchronization in digital logic circuits
• Clock buffering for memory interfaces

Procurement Notes

Verify the specific suffix 'DCG' corresponds to the SOIC-16 package and tube packaging format when sourcing. Confirm the operating temperature grade matches the commercial range (0°C to +70°C). Ensure the '-1H' designation is present to guarantee the high-drive characteristics required for signal integrity at maximum frequencies. Cross-reference the manufacturer part number with official Renesas documentation to confirm current production status.

Selection Notes

Select this component when a zero-delay buffer with low skew is required for frequencies between 10MHz and 133MHz. The -1H variant is necessary if higher output drive strength or faster edge rates are needed to maintain signal quality across longer traces. Compare against the standard 2309A-1 if lower power consumption is prioritized over drive strength. Ensure the 16-pin SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the 2309A series of PLL-based clock buffers. It is functionally related to the 2305A but offers expanded I/O capacity with 16 pins instead of fewer. The series includes variants like 2309A-1D for standard drive and 2309A-1HPGG in TSSOP packages. The 2309A-1HDCG specifically denotes the high-drive version in the SOIC-16 tube package.

Replacement Considerations

Direct substitutes include other parts from the 2309A family such as the 2309A-1D for standard drive applications or the 2309A-1HPGG if a TSSOP package is preferred. Verify that any replacement maintains the 1:9 fan-out ratio and 3.3V operation voltage.
