MAX14830
General Description
Quad Serial UART with 128-Word FIFOs
Benefits and Features
The MAX14830 is an advanced quad universal asynchro-
nous receiver-transmitter (UART), each UART having
128 words of receive and transmit first-in/first-out (FIFO)
and a high-speed serial peripheral interface (SPI) or I
2
C
controller interface. A PLL and fractional baud-rate
generators allow a high degree of flexibility in baud-rate
programming and reference clock selection.
Each of the four UARTs is selected by in-band SPI/I
2
C
addressing. Logic-level translation on the transceiver and
controller interfaces allows ease of interfacing to micro-
controllers, FPGAs, and transceivers that are powered by
differing supply voltages.
Extensive features simplify transceiver control in
half-duplex communication applications. The MAX14830
features the ability to synchronize the start of individual
UART’s transmission by SPI-based triggering. On-board
timers allow programming of delays between transmitters
as well as clock generation on GPIOs.
The 128-word FIFOs have advanced FIFO control
reducing host processor data flow management.
The MAX14830 is available in a 48-pin TQFN (7mm
x 7mm) package and is specified to operate. over the
extended -40°C to +85°C temperature range.
