2309A-1HDCG8

Overview

The Renesas 2309A-1HDCG8 is a high-speed, low-phase-noise PLL-based zero delay clock buffer designed for distributing reference clocks. It accepts one LVCMOS input and provides nine LVCMOS outputs with a 1:9 ratio. Operating at 3.3V, the device supports frequencies from 10MHz to 133MHz. Key electrical parameters include an output skew of less than 250ps and cycle-to-cycle jitter under 200ps. The component is housed in a 16-pin SOIC package (code DCG) and operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Zero Delay Buffer architecture aligns output phase with the incoming reference clock.
• Distributes one input signal to nine low-skew LVCMOS outputs.
• Supports operating frequencies up to 133MHz with <250ps output skew.
• Features on-chip PLL feedback obtained from the CLKOUT pad.

Applications

• High-speed clock distribution networks requiring low jitter.
• System synchronization where zero delay alignment is critical.
• Commercial electronic equipment operating within 0°C to +70°C.

Procurement Notes

Verify the specific suffix '8' indicates tape-and-reel packaging when sourcing. Confirm the 'A' variant designation against current datasheets to ensure compatibility with required drive strength and frequency specifications. Check moisture sensitivity level (MSL 3) requirements for storage and handling procedures prior to assembly.

Selection Notes

Select this part for applications requiring a single input to fan out to nine outputs without external components. Ensure the system voltage matches the 3.3V supply requirement. Compare against the standard 2309A-1 if lower drive strength is sufficient, or consider the -1H version for faster rise/fall times if specified by the design constraints.

Part Context

This component belongs to the 2309A series of zero delay buffers manufactured by Renesas Electronics. It serves as a clock distribution solution derived from legacy ICS technology acquired by Renesas. The device is functionally similar to other members of the family but is distinguished by its specific pinout, package type, and output count configuration.

Replacement Considerations

The IDT2309A-1HDCG8 is a direct equivalent part number. Verify pin compatibility and electrical characteristics against the current Renesas datasheet before substituting.
