IDT5T9950APFGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT5T9950APFGI is a 2.5V programmable skew PLL clock driver from the TurboClock II Jr. family, housed in a TQFP-32 package. It features four pairs of LVTTL outputs with 12mA balanced drive. The device supports input frequencies up to 200MHz for the 'A' speed grade and generates output frequencies within the same range. Key electrical parameters include low jitter (<100ps cycle-to-cycle peak-to-peak) and precise skew control (185ps max matched-pair skew). It operates over an industrial temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized Renesas or IDT distributors. Confirm the 'A' suffix indicates the 200MHz frequency grade. Check for moisture sensitivity handling requirements during storage and reflow soldering processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when precise phase alignment between multiple clock domains is required. The 'A' variant is necessary for designs operating above 160MHz. Ensure VDD and VDDQ supplies are regulated at 2.5V for optimal performance.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the IDT5T9950 series, designed as a high fanout clock driver. It utilizes a Phase Locked Loop (PLL) architecture with external feedback capabilities to maintain signal integrity across complex board layouts.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must support 2.5V operation and similar skew specifications. Verify pin compatibility with the TQFP-32 package if substituting with other programmable clock drivers.
