IDT2308-5HDCI

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT2308-5HDCI is a high-speed phase-lock loop (PLL) clock multiplier manufactured by Renesas Electronics Corporation. It operates at 3.3V and supports frequencies from 10MHz to 133.3MHz with a maximum output of 66.67MHz. The device distributes one reference input to two banks of four outputs, providing a Reference/2 frequency for both banks. Key electrical parameters include output skew under 200ps, cycle-to-cycle jitter under 200ps, and a power-down current below 25µA. It utilizes an external feedback pin for zero-delay synchronization and is housed in a 16-pin SOIC package.

• PC motherboards and workstations

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering code against the manufacturer's documentation to confirm the specific package type and temperature range. The 'DC' suffix indicates a commercial grade 16-pin SOIC package. Confirm RoHS compliance status as non-green parts have reached end-of-life per PDN U-09-01.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a half-frequency output is required for both output banks. The -5H variant provides high drive strength suitable for larger loads compared to standard drive versions. Ensure the application requires a maximum output frequency of 66.67MHz, as higher frequencies are not supported by this specific configuration.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the IDT2308 family of zero-delay clock multipliers. Unlike other variants such as the IDT2308-1 or IDT2308-4 which offer different multiplication ratios, the IDT2308-5H specifically divides the input frequency by two for all outputs. It shares the same functional block diagram and control logic as the rest of the series.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes within the same family include IDT2308-5HPG (TSSOP package) or industrial grade IDT2308-5HDCI*. Cross-model replacements like IDT2308-1H require verification of frequency multiplication requirements.
