23S05E-1HDCG

Overview

The Renesas 23S05E-1HDCG is a high-speed phase-locked loop (PLL) clock buffer designed for zero-delay clock distribution. It accepts one reference input and drives four low-skew outputs, operating within a frequency range of 10MHz to 133MHz. The device features an on-chip PLL that locks to the input clock, ensuring phase alignment between incoming and output signals. In the absence of an input clock, the device enters a power-down mode with tri-stated outputs. It is characterized for commercial operation temperatures.

Feature Summary

• Zero delay operation via on-chip PLL feedback
• Four low-skew LVCMOS outputs with 25 mA drive capability
• Operates at frequencies from 10 MHz to 133 MHz
• Tri-state mode for board-level testing

Applications

• High-speed clock distribution networks
• System-on-chip (SoC) clocking solutions
• Digital signal processing systems

Procurement Notes

Verify the specific suffix 'E' against official Renesas documentation to confirm if it denotes a specific tape-and-reel packaging variant or a distinct qualification level compared to the standard 'DCG' tube package. Ensure the commercial temperature grade aligns with system requirements.

Selection Notes

Select this component when zero propagation delay between input and output clocks is required. The -1H designation indicates higher drive strength and faster rise/fall times suitable for demanding loads. Verify that the 3.3V supply voltage and LVCMOS output levels match the receiving logic inputs.

Part Context

The 23S05 series serves as a compact alternative to the 16-pin 23S09, providing four outputs in an 8-pin SOIC package. It belongs to the IDT/Renesas family of zero-delay buffers utilizing proprietary low-jitter PLL techniques for high-performance timing applications.

Replacement Considerations

The 23S05-1HDCGI is the industrial temperature grade equivalent (-40°C to +85°C). For applications requiring more outputs, the 23S09-1HDCG provides nine outputs in a 16-pin package.
