2308B-4DCG

Overview

The Renesas 2308B-4DCG is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution applications. It operates within a frequency range of 10 MHz to 133 MHz and accepts LVCMOS input signals. The device provides eight LVCMOS outputs organized into two independent banks of four, allowing separate control via select addresses. Key electrical specifications include a maximum output skew of 200 ps and cycle-to-cycle jitter under 200 ps peak-to-peak. It functions on a single 3.3 V supply voltage and is housed in a 16-pin SOIC package.

Feature Summary

• Zero-delay PLL architecture aligns output phase with the incoming clock input
• Eight LVCMOS outputs divided into two independently controllable banks
• External feedback pin enables synchronization between input and output clocks
• Supports multiple multiplication ratios including 1x, 2x, and 4x configurations

Applications

• High-speed clock distribution networks
• System synchronization requiring low jitter
• Multiplication of reference clocks up to 133 MHz

Part Context

This component belongs to the 2308B series of zero-delay buffers manufactured by Renesas Electronics. The part number suffix '4' indicates specific prescaling and multiplication options available within this family. The device is characterized for commercial operation temperatures ranging from 0°C to +70°C.

Replacement Considerations

Public documentation identifies IDT2308B-4DCG as an alias for this part number. Designers should verify that replacement units match the 16-SOIC package dimensions and electrical characteristics of the original specification.
