2308A-1DCG8

Overview

The Renesas Electronics Corporation 2308A-1DCG8 is a Zero Delay Buffer IC designed for clock distribution applications. It operates at a maximum frequency of 133MHz with a 1:5 input-to-output ratio. The device accepts LVTTL input signals and provides CMOS, LVCMOS, or TTL outputs. It functions within a supply voltage range of 3V to 3.6V and is characterized for commercial operation between 0°C and 70°C. The component is housed in an 8-SOIC package (0.154 inch width) and supports surface mount installation.

Feature Summary

• Zero delay buffer architecture synchronizing output phase to the input clock
• Supports frequencies up to 133MHz with 1:5 distribution ratio
• LVTTL input compatibility with CMOS/LVCMOS/TTL output options
• Operates on a single 3V to 3.6V power supply

Applications

• High-speed clock distribution networks
• System synchronization requiring zero skew
• Digital logic timing alignment

Procurement Notes

Verify the specific suffix 'DCG8' corresponds to the 8-SOIC package configuration. Confirm the 'A' variant designation against official Renesas documentation to ensure correct electrical characteristics and revision level. Check RoHS compliance status as per current manufacturing data sheets before procurement.

Selection Notes

Select this component when a single LVTTL source must drive five CMOS-compatible loads with minimal propagation delay variation. Ensure the operating environment remains within the 0°C to 70°C commercial temperature range. Verify that the 3V to 3.6V supply voltage aligns with the target system's power rails.

Part Context

This part belongs to the IDT 2305/2308 family of zero-delay buffers manufactured by Renesas Electronics. These devices are engineered to eliminate clock skew by feeding back the output clock to the PLL input, ensuring the output edges align precisely with the rising edge of the input reference clock.
