2308-2DCGI8

Overview

The Renesas 2308-2DCGI8 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 10 MHz to 133 MHz, utilizing an external feedback pin to synchronize outputs with the input clock. The device features two banks of four outputs each, allowing independent control via select addresses. It supports 1x, 2x, and 4x output options and includes test mode functionality where the PLL is bypassed. The component is housed in a 16-pin SOIC package.

Feature Summary

• Zero-delay buffer architecture aligns output phase with input clock
• Operates at frequencies from 10 MHz to 133 MHz
• Two independent output banks with separate enable controls
• Supports 1x, 2x, and 4x multiplication ratios

Applications

• High-speed clock distribution networks
• System synchronization requiring low skew
• Test mode operation for system verification

Procurement Notes

Verify current availability status as this component may be discontinued or subject to supply constraints. Confirm package type and moisture sensitivity level requirements against manufacturing capabilities. Ensure compatibility with existing PCB footprint and thermal management specifications before procurement.

Selection Notes

Select based on required multiplication ratio (1x, 2x, or 4x) and operating frequency range up to 133 MHz. Consider the 16-pin SOIC package dimensions and pitch when designing the layout. Verify that the 3.3V supply voltage matches the system power rails and check if spread spectrum input capability is needed for EMI reduction.

Part Context

This part belongs to the 2308 series of zero-delay clock multipliers from Renesas Electronics. It shares architectural similarities with other variants like the 2308A and 2308B, differing primarily in specific configuration options and package types. The series is designed for applications requiring precise clock alignment and low jitter performance.

Replacement Considerations

Check for direct substitutes within the 2308 family such as the 2308-2DCG or 2308B-2DCG. Verify pinout compatibility and electrical parameters including jitter and skew specifications. Ensure any replacement part meets the same temperature range and voltage requirements.
