2305B-1PGG

Overview

The Renesas 2305B-1PGG is a 3.3V zero-delay clock buffer featuring a low phase noise PLL and five LVCMOS outputs. It operates within a frequency range of 10 MHz to 133 MHz, ensuring input-to-output propagation delay of 0 ps. The device provides four low-skew outputs with skew less than 250 ps and inter-device skew under 700 ps. Powered by a 3.3 V supply, it delivers 25 mA drive capability at TTL levels. Packaged in a 16-pin TSSOP, it supports industrial temperature ranges and includes tri-state functionality for board-level testing.

Feature Summary

• Zero-delay operation using on-chip PLL feedback from CLKOUT pad
• Five LVCMOS outputs with 25 mA drive strength
• Low skew characteristics: <250 ps output-to-output, <700 ps device-to-device
• Tri-state mode support for system testing

Applications

• High-speed digital signal processing systems
• Telecommunications infrastructure equipment
• Network switching and routing hardware

Procurement Notes

Verify the specific suffix 'PGG' against official Renesas documentation to confirm package dimensions and pinout compatibility. Ensure the operating voltage matches the 3.3 V requirement and check for lead-free compliance status in current manufacturing notices.

Selection Notes

Select this component when zero propagation delay between input and output clocks is critical. The 2305B variant offers higher drive current compared to standard versions. Confirm that the 133 MHz maximum frequency meets system timing requirements and that the TSSOP-16 footprint fits the PCB layout constraints.

Part Context

This part belongs to the IDT 2305 family of zero-delay buffers, now manufactured by Renesas Electronics following acquisition. The 2305 series is designed for low jitter applications requiring precise clock distribution without added latency.

Replacement Considerations

Direct substitutes include the 2305-1HDCGI8 for SOIC-8 packages or other 2305 family members with compatible pinouts. Verify electrical parameters such as drive strength and skew specifications before cross-referencing.
