Description:The 9161A-01 is a fully programmable graphics clock generator. It can generate user-specified clock frequencies using an externally generated input reference or a single crystal. The output frequency is programmed by entering a 24-bit digital word through the serial port. Two fully user-programmable phaselocked loops are offered in a single package. One PLL is designed to drive the memory clock, while the second drives the video clock. The outputs may be changed on-the-fly to any desired frequency between 3
Renesas provides a recommended PCB layout guide in their application notes (e.g., AN1841) and evaluation board documentation. It's essential to follow these guidelines to ensure optimal performance, especially for high-frequency signals and power supply decoupling.
The 9161A-01CW16LF has built-in POR and BOD circuits. To implement them correctly, ensure that the power supply voltage (VCC) rises slowly and monotonically during power-up, and that the reset pin (RST) is properly connected to a capacitor and a pull-up resistor. Refer to the datasheet and application notes for specific guidelines.
The 9161A-01CW16LF has a maximum junction temperature (TJ) of 150°C. To ensure reliable operation, it's essential to provide adequate heat dissipation through proper PCB design, thermal vias, and heat sinks (if necessary). Refer to the thermal management section in the datasheet for more information.
The 9161A-01CW16LF has a flexible clock system that can be configured using the Clock Control Unit (CCU). Refer to the datasheet and application notes for guidance on selecting the appropriate clock source, configuring the oscillator, and optimizing clock settings for your specific application.
To ensure EMC and EMI compliance, follow proper PCB design practices, such as using ground planes, shielding, and decoupling capacitors. Additionally, ensure that the device is properly configured and operated within its specified frequency range. Refer to the datasheet and application notes for more information.
