2308B-1HDCGI8

Overview

The Renesas Electronics Corporation 2308B-1HDCGI8 is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution. It operates within a frequency range of 10 MHz to 133 MHz, utilizing a 3.3V supply voltage. The device features an LVCMOS input and output interface, providing eight outputs organized into two independent banks of four. Key electrical specifications include a maximum output skew of less than 200 ps and cycle-to-cycle jitter under 200 ps. The component is housed in a 16-pin SOIC package and supports commercial temperature operation from 0°C to 70°C.

Feature Summary

• Zero-delay PLL architecture aligns output phase with the incoming clock input
• Distributes one clock input to two separate banks of four outputs each
• Supports 1x multiplication ratio with external feedback pin for synchronization
• Low jitter performance with output skew less than 200 ps

Applications

• High-speed clock distribution networks requiring precise phase alignment
• System synchronization where zero delay between input and output clocks is critical
• Digital circuits operating within the 10 MHz to 133 MHz frequency range

Part Context
