2305A-1DCG

Overview

The Renesas 2305A-1DCG is a zero-delay clock buffer IC designed for high-speed clock distribution. It accepts one reference input and drives five low-skew outputs, operating at frequencies from 10 MHz to 133 MHz. The device utilizes an on-chip PLL to align output phase with the input, achieving zero propagation delay. It operates within a supply voltage range of 3 V to 3.6 V and is housed in an 8-pin SOIC package. The component supports LVTTL inputs and CMOS/LVCMOS/TTL outputs.

Feature Summary

• Zero-delay operation via internal PLL feedback
• Five low-skew outputs with skew less than 250 ps
• Operating frequency range of 10 MHz to 133 MHz
• Single-supply operation at 3.3 V (3 V to 3.6 V)

Applications

• SDRAM clock distribution
• Telecommunications equipment
• Datacom systems
• PC motherboards and workstations

Part Context

The 2305A series is part of Renesas' zero-delay buffer family, derived from IDT technology acquired by Renesas. This specific model represents the standard drive version of the 2305A, distinct from the -1H high-drive variant. It is packaged in an 8-pin SOIC format suitable for surface-mount assembly.
