General Description

The  MAX3107  is  an  advanced  universal  asynchronous receiver-transmitter  (UART)  with  128 words  each  of receive  and  transmit  first-in/first-out  (FIFO)  that  can  be controlled through I2C or high-speed SPI™. The 2x and 4x rate modes allow a maximum of 24Mbps data rates. A  phase-locked  loop  (PLL),  prescaler,  and  fractional baud-rate generator allow for high-resolution baud-rate programming  and  minimize  the  dependency  of  baud rate on reference clock frequency.
