2308A-1HDCG8

Overview

The Renesas 2308A-1HDCG8 is a 3.3V zero-delay clock multiplier IC from the 2308B family, designed for high-speed clock distribution and multiplication applications. It utilizes a phase-lock loop (PLL) to align the phase between incoming and output clocks, operating within a frequency range of 10 MHz to 133 MHz. The device features two banks of four outputs each, controlled via select addresses, with separate output enable capabilities. It supports 1x multiplication options and includes test mode functionality where the PLL is bypassed. The component operates at 3.3V VDD and is characterized for commercial temperature ranges.

Feature Summary

• Zero-delay PLL architecture synchronizes output phase to input clock
• Operates at frequencies from 10 MHz to 133 MHz
• Two independent banks of four LVCMOS outputs each
• External feedback pin allows user-controlled delay adjustment

Applications

• High-speed clock distribution systems
• Clock multiplication for digital logic interfaces
• System testing environments requiring direct clock drive

Part Context

This component belongs to the IDT/Renesas 2308 series of zero-delay buffers. The '2308A' designation typically indicates specific prescaling or multiplication configurations within the broader 2308B family line, which offers various multipliers (1x, 2x, 4x). The suffix 'HDCG8' denotes the package type (SOIC-16), lead-free status, and tape/reel packaging quantity.
