The recommended layout and routing for the MAX3109ETJ+T involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the MAX3109ETJ+T and the crystal oscillator. Additionally, it is recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure the MAX3109ETJ+T is properly powered, it is recommended to use a clean and stable power supply, with a voltage range of 2.7V to 3.6V. Additionally, it is recommended to use a 10uF capacitor between the VCC pin and the GND pin to filter out any noise.
The maximum frequency of the MAX3109ETJ+T is 24MHz, but it can be overclocked up to 30MHz with reduced performance and increased power consumption.
To configure the MAX3109ETJ+T for UART mode, the UARTEN pin must be tied high, and the MODE pin must be tied low. Additionally, the TX and RX pins must be connected to the UART transmitter and receiver, respectively.
The maximum data rate of the MAX3109ETJ+T is 921.6kbps in UART mode, and 1Mbps in SPI mode.
