2308B-1HPGGI8

Overview

The Renesas 2308B-1HPGGI8 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, aligning the phase between the incoming clock and output clocks. The device features two banks of four outputs each, controlled via select addresses, with an external feedback pin to synchronize outputs. It supports 1x multiplication and includes tri-state capabilities for power-down modes drawing less than 25 µA.

Feature Summary

• Zero-delay PLL architecture synchronizes output phase to input clock
• Operates at frequencies from 10 MHz to 133 MHz
• Two independent output banks of four outputs each
• Low jitter performance with cycle-to-cycle jitter under 200 ps

Applications

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

Part Context

The 2308B-1HPGGI8 belongs to the 2308B series of zero-delay clock multipliers. This series offers multiple configurations for prescaling and multiplication, including variants like -1H, -2H, and -5H for high-drive requirements. The device is characterized for commercial operation and is available in TSSOP packages.

Replacement Considerations
