Description:9FG108 is a Synthesizer that provides 8 differential output pairs that are compliant to the Intel CK410 specification. It also provides support for PCI-Express, next generation I/O, and SATA. The part synthesizes several output frequencies from either a 14.31818 MHz crystal or a 25 MHz crystal. The device can also be driven by a reference input clock instead of a crystal. It provides outputs with cycle-to-cycle jitter of less than 50 ps and output-to-output skew of less than 65 ps.
Renesas provides a recommended PCB layout guide in their application note (R01AN4333EJ0100) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
Renesas recommends a specific power sequencing scheme in their application note (R01AN4333EJ0100) to ensure proper device operation. The sequence involves powering up the VCC, then the VDD, and finally the AVCC and DVCC.
Renesas provides guidelines for EMI and noise reduction in their application note (R01AN4333EJ0100), including the use of decoupling capacitors, ferrite beads, and shielding. Additionally, they recommend following the IEC 61967-1 standard for EMI testing.
Renesas provides power-saving techniques in their application note (R01AN4333EJ0100), such as using the low-power mode, reducing clock frequencies, and optimizing the peripheral usage. Additionally, they recommend using the device's built-in power management features, such as the Power Management Controller (PMC).
Renesas recommends following the thermal design guidelines in their application note (R01AN4333EJ0100) for high-temperature environments, including the use of thermal interfaces, heat sinks, and thermal vias. Additionally, they suggest monitoring the device's junction temperature and adjusting the thermal design accordingly.
