IDT5V928PGGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT5V928PGGI is a programmable clock generator manufactured by Renesas Electronics Corporation. It belongs to the VersaClock family and is designed for high-performance data-communications, telecommunications, consumer, and networking applications. The device features multiple internal phase-locked loops (PLLs) that allow for the generation of unique non-integer-related frequencies from a single reference clock. It supports I2C or JTAG interfaces for in-system programming and includes an internal EEPROM to retain configuration settings across power cycles. The component operates within an industrial temperature range and utilizes a TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as availability may vary by distributor. Confirm the presence of the internal EEPROM and supported interface protocols (I2C/JTAG) against the latest datasheet revision. Check for any product change notices (PCN) regarding lead-free status or manufacturing site changes prior to procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple independent frequency outputs are required from a single reference source. Ensure the design accommodates the necessary I2C or JTAG programming interface. Verify that the output voltage levels and drive strengths meet the load requirements of the downstream clock receivers. Consider the thermal performance within the specified industrial temperature range during board layout.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part is part of the IDT VersaClock series, which provides programmable clock solutions for various digital applications. It succeeds earlier fixed-frequency or less flexible clock generators by offering software-configurable parameters. The integration of EEPROM reduces system complexity by eliminating external configuration memory components.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations
