2308B-2DCGI8

Overview

The Renesas Electronics Corporation 2308B-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 133.3 MHz, providing a 1:8 frequency ratio. The device features two banks of four outputs each, controlled via select addresses, with output skew less than 200 ps and cycle-to-cycle jitter under 200 ps. Packaged in a 16-SOIC format, it supports LVTTL inputs and outputs.

Feature Summary

• Zero Delay Buffer architecture synchronizes outputs to the input clock phase
• Supports 1x, 2x, and 4x multiplication ratios via address selection
• Low jitter performance with <200 ps cycle-to-cycle specification
• Two independent output banks allow separate enable control

Applications

• High-speed clock distribution networks
• System synchronization requiring low skew
• Multiplication of reference clocks up to 133.3 MHz

Procurement Notes

This component is classified as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus inventory. No new production units are expected from the original source.

Selection Notes

Select this part for single-input, eight-output clock multiplication tasks requiring zero-delay alignment. Ensure the design accommodates the 16-SOIC package dimensions and 3.3V supply requirements. Verify that the required frequency range falls within the 10 MHz to 133.3 MHz operational limits.

Part Context

The 2308B series comprises several variants offering different multiplication factors (1x, 2x, 4x) and drive strengths. The -2 suffix typically denotes specific frequency multiplication capabilities within the family. This model belongs to the legacy IDT product line now managed by Renesas Electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official Renesas replacement notices or contact authorized distributors for cross-reference recommendations due to the component's obsolete status.
