Description:IDT954206 is a CK410M Compliant clock synthesizer. IDT954206 provides a single-chip solution for mobile systems built with Intel P4-M processors and Intel mobile chipsets. IDT954206 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 recommended PCB layout guide in their application note (APL-AN-1201) which includes thermal design considerations, such as thermal vias, copper pours, and component placement, to ensure optimal thermal performance.
Renesas recommends a specific power sequencing scheme to ensure proper device operation. This involves powering up the VCC pin first, followed by the VDD pin, and then the AVCC pin. A detailed power sequencing diagram is available in the datasheet.
Renesas recommends using 0.1uF to 1uF decoupling capacitors with a voltage rating of 10V or higher, placed as close as possible to the power pins (VCC, VDD, and AVCC) to minimize noise and ensure stable operation.
Renesas provides a JTAG interface for debugging and testing purposes. During production testing, it's recommended to use a JTAG adapter or a boundary scan tool to access the device's internal registers and perform testing. Renesas also provides a JTAG programming guide for reference.
The thermal resistance values for the 954206BGLF package are not explicitly stated in the datasheet. However, Renesas provides a thermal resistance calculator tool on their website, which can be used to estimate the thermal resistance values based on the package dimensions and material properties.
