2309A-1DCGI

Overview

The Renesas Electronics Corporation 2309A-1DCGI is a low phase noise, high-speed PLL-based zero delay buffer designed for clock distribution. It accepts one reference input and drives nine low-skew outputs at frequencies up to 133 MHz with a 3.3V supply. The device features an on-chip PLL that aligns the output phase with the input clock, achieving zero delay. It operates within a temperature range of -40°C to 85°C and is housed in a 16-pin SOIC package (Code: DCG16) with dimensions of 9.9 x 3.9 x 1.5 mm and a pitch of 1.27 mm.

Feature Summary

• Zero delay buffer architecture using proprietary low jitter PLL techniques
• Distributes one input clock to nine LVCMOS/LVTTL outputs
• Operating frequency range from 10 MHz to 133 MHz
• Output skew less than 250 ps
• Cycle-to-cycle jitter less than 200 ps

Applications

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

Procurement Notes

Verify the specific suffix 'DCGI' against the manufacturer's current datasheet to confirm pinout compatibility and electrical characteristics. Ensure the procurement source provides documentation confirming the Industrial temperature grade (-40°C to 85°C). Cross-reference the 16-SOIC package dimensions and lead count to prevent assembly errors during PCB design.

Selection Notes

Select the 2309A-1DCGI when a zero-delay phase alignment between input and output clocks is required for frequencies up to 133 MHz. Choose this part over the standard drive version if lower output skew is critical. Verify that the system power supply is stable at 3.3V and that the load requirements match the standard drive capabilities of the '-1' variant rather than the higher drive '-1H' version.

Part Context

The 2309A series is a family of high-speed clock buffers derived from the earlier 2305A/2309 designs. The 2309A-1DCGI represents the industrial temperature grade variant of the base 2309A-1 model. It shares the same core PLL functionality but is characterized for wider environmental operating ranges compared to commercial variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Evaluate other members of the 2309A family or equivalent zero-delay buffers from other manufacturers only after verifying pinout and electrical parameter compatibility.
