The recommended layout and routing for the MAX3100CPD+ involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the MAX3100CPD+ and the crystal oscillator. Additionally, it is recommended to use a low-ESR capacitor for the VCC bypass and to place the capacitor as close as possible to the VCC pin.
To ensure reliable startup of the MAX3100CPD+, it is recommended to use a high-quality crystal oscillator with a high-frequency stability, to use a suitable value for the startup capacitor (CST), and to ensure that the power supply voltage (VCC) is stable and within the recommended range.
The maximum frequency of operation for the MAX3100CPD+ is 24MHz, but it can be operated at frequencies up to 30MHz with reduced performance and increased power consumption.
To configure the MAX3100CPD+ for UART mode, the UARTEN pin must be tied high, the TXEN pin must be tied low, and the RXEN pin must be tied high. Additionally, the baud rate must be set using the BAUDRATE pins and the data format must be set using the DATAFORMAT pins.
The maximum data rate supported by the MAX3100CPD+ is 1Mbps in UART mode and 2Mbps in SPI mode.
