23S08-2HDCGI

Overview

The 23S08-2HDCGI is a 3.3V Zero Delay Clock Multiplier from the Renesas 23S08 family, designed for high-speed clock distribution and multiplication applications. It operates within an input frequency range of 10 MHz to 133 MHz using LVCMOS inputs. The device features one input and eight outputs organized into two banks, supporting multiply/divide values of 1 or 2. Key electrical specifications include a maximum cycle-to-cycle jitter of 200 ps and output skew of 200 ps. It accepts spread spectrum inputs and functions in commercial temperature ranges (0°C to 70°C). The component is housed in a 16-pin SOIC package with a pitch of 1.27 mm.

Feature Summary

• Zero delay PLL architecture synchronizes output phase with input clock
• Supports 1x and 2x multiplication/divide ratios via address pins
• Accepts spread spectrum input signals for EMI reduction
• Low jitter performance with max 200 ps cycle-to-cycle jitter

Applications

• High-speed clock distribution networks
• System synchronization requiring zero delay alignment
• Spread spectrum clock generation for EMI mitigation

Procurement Notes

Verify the suffix 'I' indicates industrial temperature rating if required, as standard 23S08 variants listed are commercial grade (0-70°C). Confirm package type matches SOIC (DCG) rather than TSSOP. Check current status as the base 23S08 series is marked obsolete in some distributor databases; ensure availability through authorized channels or alternative stock sources.

Selection Notes

Select this part when zero delay synchronization between input and multiple output clocks is critical. Ensure the system requires 1x or 2x multiplication only, as other ratios like 4x require different variants (e.g., -3H). Verify that the 3.3V supply voltage and LVCMOS interface levels match the target board design. Consider the 16-pin SOIC footprint constraints during PCB layout.

Part Context

The 23S08-2HDCGI belongs to the IDT/Renesas 23S08 family of zero-delay clock multipliers. This family provides flexible clock distribution solutions with external feedback loop control. The '-2' suffix denotes support for 1x and 2x multiplication factors, while 'DCG' specifies the 16-pin SOIC package. The 'I' suffix typically denotes extended temperature range in Renesas nomenclature, though datasheets often list commercial range for standard parts.

Replacement Considerations

Direct replacements include other 23S08 variants such as 23S08-2HDCG (commercial temp) or 23S08-1HPGG (TSSOP package, 1x only). For 4x multiplication needs, consider the 23S08-3 series. Verify pin compatibility and voltage levels before substituting.
