IDT5V9885PFGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT5V9885PFGI is a 3.3V EEPROM programmable clock generator featuring three internal PLLs for generating unique non-integer-related frequencies from a single reference. It supports input frequencies from 1MHz to 400MHz and output frequencies from 4.9kHz to 500MHz. The device includes an internal non-volatile EEPROM for configuration storage, JTAG boundary scan, and I2C serial interfaces. Outputs support LVTTL, LVCMOS, LVPECL, and LVDS standards. It operates within the industrial temperature range of -40°C to +85°C and is housed in a 32-pin TQFP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm that the 32-TQFP package matches the design requirements. Ensure compatibility with the 3.3V supply voltage and industrial temperature range specifications during sourcing.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple independent clock frequencies are required from a single reference source. Verify that the output interface requirements (LVTTL, LVDS, or LVPECL) align with the available output banks. Consider the need for spread spectrum modulation or fractional divide ratios for jitter optimization.
