2308A-1HDCGI

Overview

The Renesas Electronics Corporation 2308A-1HDCGI is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution applications. Operating within a frequency range of 10MHz to 133MHz, this device accepts one reference input and distributes the clock signal to two banks of four outputs each. It features separate output enable controls for each bank and utilizes an external feedback pin to synchronize outputs with the input clock. The component operates on a 3.3V supply voltage and is housed in a 16-SOIC package.

Feature Summary

• Zero-delay PLL architecture aligns output phase with the incoming clock input
• Distributes one clock input to two independent banks of four outputs
• Supports 1x multiplication ratio with cycle-to-cycle jitter less than 200 ps
• External feedback pin allows user control over delay between input and outputs

Applications

• High-speed clock distribution systems
• Clock multiplication and buffering for digital circuits
• System testing modes requiring direct input clock drive

Part Context

The 2308A-1HDCGI belongs to the IDT/Renesas 2308 series of zero-delay clock multipliers. This family includes variants such as the 2308B and 23S08, which offer different multiplication ratios like 2x or 4x. The 2308A specifically provides a 1x output option, distinguishing it from higher-multiplication counterparts within the same product line.
