The recommended layout and routing for the DS2155LC2+ involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the device and the crystal oscillator. Additionally, it's recommended to use a 0.1uF decoupling capacitor between the VCC and GND pins.
To ensure the DS2155LC2+ is properly powered, make sure to connect the VCC pin to a stable 3.3V or 5V power supply, and decouple the power supply with a 0.1uF capacitor. Also, ensure that the power supply can provide enough current to support the device's operating current.
The recommended crystal oscillator configuration for the DS2155LC2+ involves using a 25MHz or 26MHz crystal oscillator with a load capacitance of 18pF to 22pF. The crystal oscillator should be connected between the XTAL1 and XTAL2 pins, and the XTAL1 pin should be connected to the crystal oscillator's output.
To configure the DS2155LC2+ for low-power operation, set the PD (Power-Down) pin high to enter low-power mode. In this mode, the device's power consumption is reduced, but the device still responds to incoming data. You can also use the Shutdown (SD) pin to completely power down the device.
The DS2155LC2+ supports a maximum data transfer rate of 100Mbps, making it suitable for high-speed data transmission applications.
