2305B-1DCG8

Overview

The Renesas Electronics 2305B-1DCG8 is a zero-delay clock buffer IC designed for high-speed clock distribution. It operates within a supply voltage range of 3V to 3.6V and supports maximum output frequencies up to 133MHz. The device features one input and five outputs, packaged in an 8-SOIC (0.154 inch width) surface-mount package. It utilizes a Phase-Locked Loop (PLL) to achieve zero input-to-output delay with low skew characteristics. The component is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

• Zero-delay buffering using internal PLL feedback
• Supports clock frequencies from 10MHz to 133MHz
• Five LVCMOS/TTL compatible outputs with 25mA drive capability
• Low skew performance (<250ps typical)

Applications

• High-speed data acquisition systems
• Telecommunications equipment clock distribution
• Industrial control system timing synchronization

Procurement Notes

Verify the specific suffix 'B' against official Renesas documentation, as standard listings often reference the '2305-1' series. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) prior to assembly. Ensure the 8-SOIC package dimensions match the target PCB footprint requirements.

Selection Notes

Select this component when zero input-to-output delay is critical for system timing. Compare against the 2305-1H variants if higher drive strength or faster rise/fall times are required. Verify that the 3.3V operating voltage aligns with the target logic levels and that the commercial temperature range meets environmental specifications.

Part Context

This part belongs to the IDT 2305 family of zero-delay buffers, now manufactured by Renesas Electronics following the IDT acquisition. The family includes variants such as the 2305-1 (standard drive) and 2305-1H (high drive). The 'B' suffix may indicate a specific revision or packaging configuration distinct from the standard 2305-1DCG8.

Replacement Considerations

Direct pin-compatible substitutes include the 2305-1DCG8 and 2305-1HDCGI8. Verify functional equivalence regarding drive current and skew specifications before substitution.
