2308A-3DCGI

Overview

The Renesas Electronics 2308A-3DCGI is a discontinued high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution. It operates at 3.3V and supports input frequencies from 10MHz to 133MHz, providing an output frequency of 133MHz with a 1:8 ratio. The device features eight LVCMOS outputs arranged in two banks, each with independent enable control. Key electrical specifications include a maximum output skew of 200ps and cycle-to-cycle jitter under 200ps. It utilizes an external feedback pin to synchronize outputs to the input clock, eliminating the need for external RC networks.

Feature Summary

• Zero-delay buffer architecture aligns output phase with input clock
• Eight LVCMOS outputs distributed across two independently controllable banks
• External feedback pin allows user-controlled delay between input and outputs
• Operates within 10MHz to 133MHz frequency range

Applications

• High-speed clock distribution systems
• System synchronization requiring low skew
• Test mode operation via direct input clock drive

Part Context

This component belongs to the IDT 2308 family of zero-delay clock multipliers, originally developed by Integrated Device Technology (IDT) before its acquisition by Renesas Electronics. The 'A' suffix typically denotes specific manufacturing revisions or binning within this series. The part is listed as obsolete, indicating it is no longer in active production.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative solutions require evaluation based on functional equivalence, specifically matching the 16-pin SOIC package, 3.3V supply, and 133MHz zero-delay buffer capabilities.
