IDT23S08-5HDC

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT23S08-5HDC is a 3.3V zero delay clock multiplier with high drive capability, operating within the commercial temperature range of 0°C to +70°C. It features a single LVCMOS input and eight outputs divided into two banks of four. The device supports spread spectrum inputs and provides a reference-to-reference output frequency ratio. Key electrical parameters include an output skew of less than 200 ps, cycle-to-cycle jitter under 200 ps at 66.67 MHz, and a maximum output frequency of 133.3 MHz with a 20 pF load.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the package type matches the required PCB footprint, as this model uses a 16-pin SOIC. Confirm the suffix indicates the correct temperature grade for the target environment. Check for RoHS compliance status if environmental regulations apply to the assembly process.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when high drive strength is necessary for heavy capacitive loads. Ensure the application requires a 1x multiplication factor. Verify that the system can accommodate the external PLL feedback connection on the FBK pin to achieve zero delay performance.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the IDT23S08 family of zero delay clock multipliers. The '5H' designation specifically identifies the high-drive version configured for a 1x frequency ratio. The 'DC' suffix denotes the standard plastic SOIC package format suitable for surface mount assembly.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Compatible substitutes within the same family include the IDT23S08-1HDC and IDT23S08-2HDC. These alternatives share the high-drive characteristic but differ in their available frequency multiplication options.
