2308-5HPGG

Overview

The Renesas 2308-5HPGG is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution and multiplication. Operating within a frequency range of 10MHz to 133MHz, it aligns the phase between incoming and output clocks to achieve zero delay. The device features two banks of four outputs each, controlled via select addresses, with separate enable capabilities for each bank. It operates at a 3.3V supply voltage and includes an external feedback pin to synchronize outputs to the input clock. In power-down mode without an input clock, current consumption drops below 25uA.

Feature Summary

• Zero-delay PLL operation synchronizing output phase to input clock
• Frequency range from 10MHz to 133MHz with 3.3V VDD operation
• Eight LVCMOS outputs organized in two independent banks of four
• Output skew less than 200 ps and cycle-to-cycle jitter under 200 ps

Applications

• High-speed clock distribution networks
• System synchronization requiring zero delay alignment
• Multiplication of reference clocks in digital systems

Part Context

This component belongs to the IDT/Renesas 2308 series of zero-delay buffers and multipliers. It is available in various configurations offering different prescaling and multiplication ratios, such as 1x, 2x, and 4x options. The -5H suffix typically denotes a specific configuration variant within this family, often associated with high-drive capabilities or specific multiplication factors like 2x.

Replacement Considerations

Compatible alternatives include other members of the 2308 family, such as the 2308B-5HPGG or 23S08-5HPGG, which share similar functional characteristics. Verify that the replacement part matches the required multiplication ratio and drive strength specifications.
