Description:The 9DBL0442 4-output zero-delay/fan-out buffer is a 3.3V member of Renesas' Full-Featured PCIe family. The 9DBL0442 supports PCIe Gen1 through Gen5 and both Common and Independent Reference Clock architectures. For information regarding evaluation boards and material, please contact your local sales representative.
The recommended power-up sequence is to apply VDD first, followed by VDDA, and then the input clock signal. This ensures proper initialization and prevents potential latch-up conditions.
The output frequency can be configured by selecting the appropriate values for the external resistors (R1, R2, and R3) and capacitors (C1 and C2) according to the datasheet's equations and tables. Additionally, the device's internal registers can be programmed to select the desired output frequency and configuration.
The maximum input clock frequency is 350 MHz, according to the datasheet. However, it's essential to consider the specific application's requirements and ensure that the input clock signal meets the device's input clock requirements.
To ensure the output signals are in phase, it's crucial to follow the datasheet's guidelines for output signal routing and termination. Additionally, the device's internal registers can be programmed to adjust the output phase relationships.
The typical power consumption of the 9DBL0442BKILFT is around 150 mW, depending on the specific configuration and operating conditions. However, it's recommended to consult the datasheet for more detailed power consumption information and to perform thorough power analysis for the specific application.
