2308B-2DCG8

Overview

The Renesas Electronics 2308B-2DCG8 is a 3.3V PLL zero-delay clock multiplier and buffer IC housed in a 16-SOIC package. It features an LVTTL input and eight LVTTL outputs, supporting frequencies up to 133.3 MHz with a 1:8 input-to-output ratio. The device operates within a commercial temperature range of 0°C to +70°C and draws 45 mA. Key electrical specifications include a maximum output skew of 200 ps and peak-to-peak jitter of 400 ps. This component is classified as a clock generator and is currently listed as obsolete by the manufacturer.

Feature Summary

• Zero-delay buffer architecture ensuring minimal propagation delay between input and output clocks
• Eight LVCMOS/LVTTL outputs driven from a single LVCMOS/LVTTL input
• Maximum operating frequency of 133.3 MHz with 400 ps peak-to-peak jitter
• Available in a standard 16-SOIC surface-mount package

Applications

• Clock distribution networks requiring zero-skew synchronization
• System timing generation for high-speed digital logic
• Frequency multiplication in embedded controller architectures

Procurement Notes

This component is officially marked as obsolete or end-of-life by Renesas Electronics. Availability is restricted to surplus stock held by third-party distributors. Verification of authenticity and lot traceability is critical when sourcing from non-authorized channels due to the discontinued status.

Selection Notes

Designers should verify that the 133.3 MHz maximum frequency meets system requirements. The device requires a 3.3V supply and supports LVTTL signaling levels. Consider the 200 ps output skew specification for timing-critical layouts. Alternative solutions may be necessary given the obsolescence status.

Part Context

The 2308B series belongs to Renesas' family of zero-delay clock multipliers. The '2DCG8' suffix typically denotes specific packaging (SOIC) and reel quantities (2500 units). Related variants include the 2308-3DCG and 2308A-4DCGI8, which share similar core functionalities but differ in pinout configurations or package types.

Replacement Considerations

Public documentation lists IDT2308B-2DCG as a direct substitute part number. No other cross-manufacturer replacements are verified in the provided source material.
