Description:The 5V49EE704 is a programmable clock generator intended for high performance data-communications, telecommunications, consumer, and networking applications. There are four internal PLLs, each individually programmable, allowing for four unique non-integer-related frequencies. The frequencies are generated from a single reference clock. The reference clock can come from one of the two redundant clock inputs. Automatic or manual switchover function allows any one of the redundant clocks to be selected during
Renesas provides a recommended PCB layout guide in their application note (AP-61004) for the 5V49EE704NDGI, which includes thermal vias, heat sink attachment, and PCB material selection guidelines.
Renesas recommends a specific power sequencing scheme in their datasheet, which involves powering up the VCCIO and VCC cores in a specific order. Additionally, they provide a power sequencing diagram in their application note (AP-61004).
The 5V49EE704NDGI is rated for operation up to 100°C, but Renesas recommends derating the device's performance and power consumption at higher temperatures. They provide thermal derating guidelines in their datasheet and application note (AP-61004).
Renesas provides power-saving features such as dynamic voltage and frequency scaling, as well as clock gating and power gating. They also recommend optimizing the device's configuration, reducing clock frequencies, and using low-power modes to minimize power consumption.
Renesas recommends using EMI and RFI mitigation techniques such as shielding, filtering, and grounding to minimize electromagnetic interference. They also provide guidelines for PCB layout, component selection, and signal routing to reduce EMI and RFI.
