AK8181B

The AKD8181B evaluation board has an SMA terminal input.

The AKD8181B evaluation board features: - SMA terminal input - Ability to mount a crystal - Capability to construct three types of output load circuits - Terminal and land pattern preparation for VDD/VEE - Control switches for CLK_SEL and CLK_EN - Various output pins such as Q0/Q0n, Q1/Q1n, Q2/Q2n, Q3/Q3n - Clock input options selected by CLK_SEL switch - Three power supplies: VDD, VEE, VDD-2V - Ability to terminate clock input signal at 50Ω - Ability to set up output load circuits for Q0/0N, Q1/1N, Q2/2N, and Q3/3N AKD8181B Evaluation Board.

The purpose of the AKD8181B evaluation board is to evaluate the DC/AC characteristics and confirm the product functions of the AK8181B. It allows for setting up the output load circuit of Q0/0N, Q1/1N, Q2/2N, and Q3/3N. The evaluation board provides various features such as SMA terminal input, the ability to mount a crystal, constructing three types of output load circuits, and preparing terminals and land patterns for VDD/VEE. Additionally, it includes controls for CLK_SEL and CLK_EN switches for clock input. The evaluation board also offers three power supplies - VDD, VEE, and VDD-2V, allowing evaluation without applying power to the VDD-2V terminal if a termination circuit with a resistor is configured. The clock input can be selected externally or from a crystal, with the option to terminate the clock input signal at 50Ω if needed. The output load circuit can be terminated using three methods (Pattern A/B/C), with the core power supply of AK8181B (3.3V) and GND, as well as the power supply for the end of the output load resistor (VDD-2V). It is important to note that the GND of the SMA terminal is connected to the VEE inside the substrate. Overall, the AKD8181B evaluation board serves as a tool for assessing and verifying the functionality and characteristics of the AK8181B product.
