2308-5HDCG8

Overview

The Renesas Electronics Corporation 2308-5HDCG8 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 and accepts LVCMOS input signals. The device provides eight outputs organized into two banks, each containing four outputs. It functions at a core voltage of 3.3 V and features low jitter performance with a maximum cycle-to-cycle jitter of 400 ps peak-to-peak. The component utilizes an external feedback pin to synchronize output phases with the input clock, ensuring precise timing alignment in high-speed digital systems.

Feature Summary

• Zero-delay PLL architecture synchronizes output phase with input clock
• Eight LVCMOS outputs distributed across two independently controllable banks
• Operates at frequencies from 10 MHz to 133 MHz with 3.3 V supply
• Maximum cycle-to-cycle jitter of 400 ps peak-to-peak

Applications

• High-speed clock distribution networks
• System synchronization requiring zero delay
• Digital logic circuits operating up to 133 MHz

Part Context

The 2308-5HDCG8 belongs to the IDT 2308B series of clock multipliers. This family includes variants such as 2308B-1, 2308B-2, and 2308B-3, which offer different prescaling and multiplication options. The specific suffix '5' typically denotes a particular multiplication factor configuration within this product line, distinct from other variants like the 23S08 series which supports spread spectrum inputs.

Replacement Considerations

Verify functional equivalence with other members of the 2308B family, such as the 2308B-1 or 2308B-2, depending on required multiplication factors. Ensure that alternative components support the same 3.3 V operation and LVCMOS output levels. Check package compatibility, as SOIC-16 is standard for this series.
