2308-1DCGI8

Overview

The Renesas Electronics 2308-1DCGI8 is a 3.3V PLL zero-delay clock multiplier in a 16-pin SOIC package. It functions as a high-speed phase-lock loop clock distribution device, operating within an input frequency range of 10 MHz to 133 MHz. The component provides eight LVCMOS outputs organized into two banks of four, with separate enable controls for each bank. Key electrical characteristics include output skew less than 200 ps and cycle-to-cycle jitter under 200 ps. The device supports 1x multiplication factors and features external feedback synchronization.

Feature Summary

• Zero-delay PLL architecture aligns output phase with the incoming clock input
• Distributes one clock input to two independent banks of four LVCMOS outputs
• External feedback pin allows synchronization of outputs to the clock input
• Operates at 3.3V VDD with low power consumption (less than 25uA in power down)

Applications

• High-speed clock distribution systems
• Clock multiplication applications requiring zero delay
• System testing modes using direct input clock drive

Part Context

This component belongs to the IDT/Renesas 2308 series of zero-delay clock multipliers. It is a legacy product marked as obsolete or end-of-life. The 'DCGI8' suffix indicates a 16-lead SOIC package with industrial temperature range and tape-and-reel packaging. It is part of a family that includes variants like the 2308B and 23S08.

Replacement Considerations

The 2308-1DCGI8 is listed as obsolete. Potential replacements within the same functional family include the 2308B-1DCG8 or other 2308 series variants. Verification of pin compatibility and electrical specifications against the specific datasheet revision is required before substitution.
