Description:The 5V49EE702 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-61001) for the 5V49EE702NDGI, which includes thermal management guidelines, such as using thermal vias, thermal pads, and heat sinks to ensure optimal thermal performance.
Renesas recommends a specific power sequencing scheme in their application note (AP-61001) to ensure proper device operation. The recommended sequence is: VCCIO, VCC, VCCA, and finally, VREF.
While the datasheet provides general information about the PLL, Renesas' application note (AP-61001) provides more detailed information on the PLL's frequency range (10 MHz to 650 MHz) and jitter performance (typically < 100 ps).
Renesas provides guidelines for clock tree optimization in their application note (AP-61001), including using clock gating, reducing clock frequency, and using low-power clock sources to minimize power consumption.
Renesas provides recommendations for I/O bank settings, such as output drive strength, slew rate, and termination, in their application note (AP-61001) to ensure optimal signal integrity and minimize signal degradation.
