MAX3109 - Dual Serial UART

General Description

The MAX3109 advanced dual universal asynchronous receiver-transmitter (UART) has 128 words of receive and transmit first-in/first-out (FIFO) and a high-speed SPI or I2C controller interface.

The 2x and 4x rate modes allow a maximum of 24Mbps data rates.

MAX3109 Dual Serial UART with 128-Word FIFOs General Description The MAX3109 advanced dual universal asynchronous receiver-transmitter (UART) has 128 words of receive and transmit first-in/first-out (FIFO) and a high-speed SPI or I2C controller interface. The 2x and 4x rate modes allow a maximum of 24Mbps data rates. A phase-locked loop (PLL) and the fractional baud-rate generators allow a high degree of flexibility in baud-rate programming and reference clock selection. Independent logic-level translation on the transceiver and controller interfaces allows ease of interfacing to microcontrollers, FPGAs, and transceivers that are powered by differing supply voltages.
