2308-5HDCGI

Overview

The Renesas 2308-5HDCGI is a high-speed phase-lock loop (PLL) clock multiplier designed for zero-delay clock distribution and multiplication applications. It operates within an input frequency range of 10 MHz to 133 MHz, aligning the phase between the incoming clock and output clocks. The device features two banks of four outputs each, controlled via select addresses, with separate output enable capabilities. It supports 1x, 2x, and 4x prescaling and multiplication options. Key electrical characteristics include output skew less than 200 ps and cycle-to-cycle jitter under 200 ps. The component functions at a 3.3V supply voltage and is available in SOIC packages.

Feature Summary

• Zero-delay PLL architecture synchronizes output phase with input clock
• Dual bank configuration providing eight LVCMOS outputs
• Configurable multiplication factors including 1x, 2x, and 4x
• Low jitter performance with cycle-to-cycle jitter <200 ps

Applications

• High-speed clock distribution networks
• System synchronization requiring precise phase alignment
• Digital signal processing equipment clock generation

Procurement Notes

Verify the specific suffix 'HDCGI' against official Renesas documentation to confirm package type and temperature range. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Check for obsolescence notices or product change notifications prior to procurement decisions.

Selection Notes

Select this component when zero-delay buffering is required for frequencies up to 133 MHz. Ensure the design accommodates the external feedback pin necessary for PLL closure. Verify that the 3.3V logic levels match the system requirements and that the SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the 2308 series of zero-delay clock multipliers from Renesas Electronics. The series includes variants with different multiplication ratios and drive strengths. The 2308-5HDCGI specifically denotes a configuration supporting multiple multiplication modes within the standard commercial or industrial temperature ranges depending on the full suffix.

Replacement Considerations

Consult official substitution lists for direct replacements. Generic clock buffers may not provide the zero-delay PLL functionality. Verify pin compatibility and electrical specifications before considering alternative manufacturers.
