2305-1DCG8

Overview

The Renesas Electronics Corporation 2305-1DCG8 is a Zero Delay Buffer IC designed for clock distribution applications. It operates within a supply voltage range of 3V to 3.6V and supports maximum frequencies up to 133MHz. The device features a 1:5 input-to-output ratio with LVTTL input and CMOS, LVCMOS, or TTL output types. Packaged in an 8-SOIC format (0.154" width), it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Zero delay buffering capability utilizing PLL techniques
• Low skew output generation for precise timing
• Tri-state mode support for board-level testing

Applications

• Clock distribution networks
• System synchronization
• High-speed digital circuit timing

Procurement Notes

Verify the specific suffix '8' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm RoHS3 compliance status matches current manufacturing standards. Ensure the commercial temperature grade (0°C to 70°C) aligns with system environmental requirements rather than industrial specifications.

Selection Notes

Select this component when zero-delay performance is required at frequencies up to 133MHz. The 8-SOIC package suits surface-mount assembly processes. Verify that the LVTTL input compatibility matches the source clock driver. Consider the 3V to 3.6V supply requirement against available power rails.

Part Context

This part belongs to the 2305 series of low phase noise, high-speed PLL-based buffers. It serves as a variant within the broader IDT/Renesas clock buffer portfolio, specifically engineered for low jitter applications. The device integrates on-chip feedback obtained from the CLKOUT pad to maintain signal integrity.
