23S08-3DCGI8

Overview

The Renesas Electronics 23S08-3DCGI8 is a discontinued 3.3V 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, providing eight LVCMOS outputs with a maximum output frequency of 133 MHz. The device features a 16-pin SOIC package and supports spread spectrum input compatibility. Key electrical parameters include a cycle-to-cycle jitter of 200 ps and an operating temperature range of 0°C to +70°C. It utilizes a Phase-Lock Loop (PLL) architecture to achieve zero delay between the input reference clock and the output clocks.

Feature Summary

• Zero Delay Buffer architecture aligns output phase with the incoming clock input
• Supports Spread Spectrum Input for EMI reduction
• Eight LVCMOS outputs organized into two independent banks
• Low cycle-to-cycle jitter specification of 200 ps

Applications

• High-speed clock distribution systems
• Clock multiplication for digital logic interfaces
• Systems requiring low jitter clock generation from 10 MHz to 133 MHz

Procurement Notes

The 23S08-3DCGI8 is officially listed as End-of-Life (EOL) by Renesas Electronics. Availability is restricted to existing stock or third-party distributors; direct new production orders are not supported. Verification of component authenticity and storage history is critical due to the part's obsolete status. Moisture sensitivity level (MSL) is 3, requiring adherence to floor life guidelines if the package seal has been compromised.

Selection Notes

This component is suitable for designs requiring a single input to drive multiple synchronized LVCMOS loads without external feedback networks. It is appropriate for commercial temperature ranges (0°C to +70°C). For applications requiring industrial temperature ratings (-40°C to +85°C), alternative variants such as the IDT2308-3DCI8 should be evaluated. Designers must ensure the input clock source is compatible with the LVCMOS input type and that the 3.3V supply voltage matches the system requirements.

Part Context

The 23S08 series belongs to Renesas' portfolio of PLL-based clock multipliers, formerly associated with Integrated Device Technology (IDT). This specific model represents a variant optimized for commercial use with spread spectrum capabilities. It serves as a successor or alternative to earlier generations like the 2308B, offering integrated spread spectrum support which was not standard in all previous models. The suffix 'DCGI8' denotes the specific package, temperature grade, and feature set.
