Frequently asked questions
What is the difference between the 9DBL0452BKILFT and the 9DBL0452BKILF?
The primary difference is the packaging format. The 9DBL0452BKILFT is supplied in tape and reel packaging, while the 9DBL0452BKILF is supplied in tube or tray packaging. Both part numbers refer to the same base device, the 9DBL0452B, a 4-output differential clock buffer from Renesas.
Are the 9DBL0452BKILFT and 9DBL0452BKILF electrically and functionally identical?
Yes. Both part numbers share the same base device, the 9DBL0452B. They have identical electrical specifications, functionality, pinout, and performance characteristics. The only difference is the shipping packaging format indicated by the suffix.
What does the "T" suffix indicate on the 9DBL0452BKILFT?
The "T" suffix indicates tape and reel packaging. This format is typically used for automated pick-and-place assembly lines in high-volume production. The 9DBL0452BKILF without the "T" suffix is supplied in tube or tray packaging.
Can the 9DBL0452BKILFT and 9DBL0452BKILF be used interchangeably in a design?
Yes, they are electrically and functionally interchangeable because they are the same base device. However, the physical packaging format differs, so the choice between them depends on the assembly process. Tape and reel is preferred for automated high-volume assembly, while tubes or trays may be used for prototyping or low-volume production.
What is the function of the 9DBL0452B device?
The 9DBL0452B is a 4-output differential clock buffer designed for PCIe Gen1 through Gen5 and other high-performance clock distribution applications. It provides low additive jitter and supports fanout of differential clock signals.
What package type do the 9DBL0452BKILFT and 9DBL0452BKILF use?
Both part numbers use the same package type, a 32-pin VFQFN (very thin fine-pitch quad flat no-lead) package. The package code "KIL" in the part number designates this package and temperature grade.
Do the 9DBL0452BKILFT and 9DBL0452BKILF have the same operating temperature range?
Yes. Both part numbers share the same industrial temperature range specification, as indicated by the "I" in the part number. They are rated for operation over the industrial temperature range as specified in the Renesas 9DBL0452B datasheet.
Which part number should be ordered for automated production assembly?
The 9DBL0452BKILFT should be ordered for automated production assembly because the "T" suffix denotes tape and reel packaging, which is compatible with automated pick-and-place equipment. The 9DBL0452BKILF in tube or tray packaging is more suitable for manual assembly or prototyping.
