2305A-1DCGI

Overview

The Renesas Electronics Corporation 2305A-1DCGI is a zero-delay buffer integrated circuit designed for high-speed clock distribution. It operates within a supply voltage range of 3V to 3.6V and supports input frequencies from 10MHz to 133MHz. The device features one differential input and five CMOS outputs, packaged in an 8-SOIC format. It provides low skew performance with output skew less than 250ps and cycle-to-cycle jitter under 200ps. The component is rated for industrial operating temperatures between -40°C and +85°C.

Feature Summary

• Zero-delay PLL-based architecture aligns output phase with input clock
• Five CMOS outputs with 25mA drive capability at TTL levels
• Low skew (<250ps) and low jitter (<200ps cycle-to-cycle)
• Industrial temperature range (-40°C to +85°C)

Applications

• High-speed clock distribution networks
• System synchronization in digital logic circuits
• Buffering reference clocks for FPGA or ASIC inputs

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) compared to commercial variants. Confirm package dimensions match the 8-SOIC (0.154 inch width) specification. Check RoHS compliance status as per current manufacturer documentation before integration.

Selection Notes

Select this part when zero propagation delay is critical for system timing. Ensure the input signal frequency falls within the 10MHz to 133MHz operational range. Verify that the 3.3V nominal supply voltage aligns with the system power rails. Consider the 8-pin SOIC package constraints for PCB layout.

Part Context

This component belongs to the IDT 2305 family of zero-delay buffers. It serves as a low-phase-noise, high-speed PLL-based solution for distributing a single clock input to multiple outputs. The 2305A variant typically denotes specific electrical characteristics or generation updates within the broader 2305 product line.
