Description:The 5V49EE502 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 5V49EE502NLGI, which includes thermal design considerations, such as thermal vias, heat sinks, and PCB material selection.
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-61001).
While the datasheet provides general information about the PLL, Renesas' application note (AP-61001) provides more detailed information on the PLL's frequency range and jitter performance. The PLL can operate from 10 MHz to 400 MHz, and the jitter is typically around 100 ps.
Renesas provides power-saving features such as dynamic voltage and frequency scaling, as well as clock gating. Engineers can use these features to optimize power consumption by adjusting the clock frequency, voltage, and power modes according to their application's requirements.
Renesas recommends using the internal oscillator with a 10 MHz crystal oscillator and a load capacitance of 10 pF to 20 pF. The internal oscillator can be configured using the device's configuration registers, and Renesas provides more detailed information in their application note (AP-61001).
