2305A-1HDCGI

Overview

The Renesas 2305A-1HDCGI is a zero-delay clock buffer IC designed for high-speed clock distribution. It operates within a frequency range of 10 MHz to 133 MHz using a 3 V to 3.6 V supply voltage. The device features one LVCMOS input and five LVCMOS outputs, packaged in an 8-SOIC (0.154", 3.90 mm width) housing. It supports industrial operating temperatures from -40°C to +85°C and includes tri-state capabilities for board-level testing.

Feature Summary

• Zero-delay PLL architecture aligns output phase with the reference input
• Low skew performance with output skew less than 250 ps
• Cycle-to-cycle jitter specification below 200 ps
• Tri-state mode support for system diagnostics

Applications

• High-speed clock distribution networks
• Jitter cleaning in digital systems
• Board-level clock buffering

Procurement Notes

Verify component status as discontinued or obsolete through official Renesas channels before procurement planning. Confirm that the 8-SOIC package dimensions and pinout match the target PCB footprint. Ensure the 3.3 V supply requirement and LVCMOS logic levels are compatible with the system design specifications.

Selection Notes

Select this component when a single-ended LVCMOS input must drive five low-skew outputs with minimal propagation delay. Compare against the standard drive version if lower power consumption is prioritized over signal integrity at maximum frequencies. Verify that the 133 MHz maximum frequency meets the specific application timing requirements.

Part Context

This part belongs to the 2305A series of zero-delay buffers. It serves as a 5-output variant within the family, distinct from the 2309A which provides eight outputs in a 16-pin package. The suffix 'H' indicates high-drive capability compared to the base model.
