2305-1HDCGI

Overview

The Renesas 2305-1HDCGI is a zero-delay clock buffer operating at 3.3V with an LVCMOS input and five LVCMOS outputs. It supports frequencies from 10 MHz to 133 MHz, featuring on-chip PLL feedback for zero propagation delay between input and output. The device provides low skew of less than 250 ps and cycle-to-cycle jitter under 200 ps. It operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Feature Summary

• Zero-delay operation using internal PLL feedback
• Five LVCMOS outputs with <250 ps skew
• Operating frequency range of 10 MHz to 133 MHz
• Industrial temperature rating (-40°C to +85°C)

Applications

• High-speed clock distribution systems
• SDRAM synchronization interfaces
• Telecommunications equipment
• Datacom infrastructure

Procurement Notes

Verify the specific suffix 'GI' confirms the industrial temperature grade (-40°C to +85°C) and SOIC-8 packaging. Confirm RoHS compliance status via the manufacturer's current datasheet or certification documents before procurement.

Selection Notes

Select this component when zero propagation delay is critical for system timing. Ensure the application requires single-ended LVCMOS signaling and operates within the 3V to 3.6V supply voltage range. Verify that the 133 MHz maximum frequency meets the design requirements.

Part Context

This part belongs to the IDT/Renesas 2305 family of high-speed, low-jitter clock buffers. The '-1' designation indicates the base drive version, while 'H' variants offer higher drive strength. The '2305-1HDCGI' specifically denotes the industrial grade variant in an 8-pin SOIC package.

Replacement Considerations

The 2305NZ-1HDCGI is a related variant within the same product family. Verify pinout compatibility and electrical specifications against the target application requirements before substitution.
