Description:The 5V49EE904 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 5V49EE904NLGI, which includes thermal design considerations, such as thermal vias, heat sinks, and PCB material selection.
Renesas recommends a specific power sequencing scheme in their application note (AP-61004) to ensure proper device operation. The sequence involves powering up the VCCIO, VCC, and VTT rails in a specific order, with specific timing requirements.
The recommended PLL settings can be found in the Renesas FPGA Development Environment (FDE) software, which provides a PLL configuration tool. The tool helps optimize PLL settings for specific clock frequencies and jitter requirements.
Renesas provides power optimization guidelines in their application note (AP-61004), which include techniques such as clock gating, voltage scaling, and dynamic voltage and frequency scaling (DVFS). Additionally, the FDE software provides power analysis tools to help optimize power consumption.
The BIST feature in the 5V49EE904NLGI is limited to testing the device's internal logic and memory. It does not test external interfaces, such as I/O pins or external memory. Additionally, BIST may not detect all possible faults or errors, and should be used in conjunction with other testing methods.
