2308A-1HPGG8

Overview

The Renesas Electronics 2308A-1HPGG8 is a 3.3V PLL zero-delay clock multiplier designed for high-speed clock distribution and multiplication applications. It operates within a frequency range of 10MHz to 133MHz, distributing one clock input to two banks of four outputs. The device achieves zero delay by synchronizing output phases with the input clock via an external feedback pin. Key electrical parameters include a maximum operating frequency of 133 MHz, a cycle-to-cycle jitter of less than 200 ps, and an output skew of less than 250 ps. It functions at 3.3V VDD and supports 1x output multiplication options.

Feature Summary

• Phase-Lock Loop (PLL) clock distribution supporting frequencies from 10MHz to 133MHz
• Zero-delay operation achieved through external feedback synchronization
• Eight push-pull CMOS outputs organized into two independent banks of four
• Low jitter performance with cycle-to-cycle jitter under 200 ps

Applications

• High-speed clock distribution networks
• Clock multiplication systems requiring phase alignment
• Commercial and industrial electronic equipment

Part Context

The 2308A-1HPGG8 belongs to the IDT/Renesas 2308 series of zero-delay clock multipliers. This family addresses the need for precise clock timing in digital systems by eliminating propagation delay between input and output clocks. The 'A' suffix typically denotes specific commercial temperature range variants within the broader product line.

Replacement Considerations

The 2308B-1HPGG8 is a documented alternative within the same product family offering similar zero-delay multiplication capabilities. Verification of exact electrical specifications and package compatibility is required before substitution.
