Description:IDT954226 is a CK410M Compliant clock synthesizer. IDT954226 provides a single-chip solution for mobile systems built with Intel P4-M processors and Intel mobile chipsets. IDT954226 is driven with a 14.318MHz crystal and generates CPU outputs up to 400MHz. It provides the tight ppm accuracy required by Serial ATA and PCI Express.
Renesas provides a reference design guide for the 954226AGLFT, which includes recommendations for PCB layout, thermal management, and component placement to ensure optimal performance and thermal dissipation.
Renesas recommends using a power management IC (PMIC) specifically designed for the 954226AGLFT, such as the Renesas ISL91211A, to ensure proper power sequencing and voltage regulation. The PMIC datasheet provides detailed guidance on implementation.
Renesas recommends using high-quality, low-ESR decoupling capacitors with a value of 10uF to 22uF, placed as close as possible to the device's power pins. The capacitors should be rated for high-frequency operation and have a low inductance to minimize noise and ripple.
Renesas provides guidelines for EMC and EMI reduction in the 954226AGLFT application note, including recommendations for PCB layout, shielding, and filtering. Additionally, Renesas offers EMC-compliant reference designs and evaluation boards.
Renesas provides thermal design guidelines and a thermal model for the 954226AGLFT in the datasheet and application note. The junction temperature can be calculated using the provided thermal resistance values and the device's power consumption.
