2308A-2DCGI8

Overview

The Renesas Electronics Corporation 2308A-2DCGI8 is a 3.3V PLL zero-delay clock multiplier designed for high-speed clock distribution and multiplication applications. It operates within an input frequency range of 10 MHz to 133 MHz, distributing one clock input to two banks of four outputs each. The device achieves zero delay by aligning the phase between the incoming clock and the output clock. It features separate output enable controls for each bank, allowing both to be tri-stated via select addresses. The component is housed in a 16-pin SOIC package.

Feature Summary

• Zero-delay phase alignment between input and output clocks
• Two independent banks of four LVCMOS outputs each
• External feedback pin for precise synchronization control
• Output skew less than 200 ps with cycle-to-cycle jitter under 200 ps

Applications

• High-speed clock distribution systems
• Clock multiplication for digital logic interfaces
• System testing modes requiring direct input clock drive

Procurement Notes

Verify component authenticity through authorized channels as this part number may have limited availability. Confirm moisture sensitivity level (MSL) handling requirements prior to assembly. Ensure the specific suffix matches the required packaging format for production integration.

Selection Notes

Select this model when a 2x multiplication factor is required alongside 1x options. Verify that the 3.3V operating voltage and LVCMOS output levels match the target system's power rails and logic thresholds. Consider the external feedback loop requirement for minimizing delay variations.

Part Context

This component belongs to the IDT 2308 family of zero-delay buffers. It shares architectural similarities with variants like the 2308-3DCG but differs in its specific prescaling and multiplication configuration capabilities defined by the '2' suffix.

Replacement Considerations

Direct substitutes include other members of the 2308 series such as the 2308-1DCGI8 or 2308-4DCGI8, provided the multiplication factors align with design requirements. Cross-reference pinouts and electrical specifications before substitution.
