SC16C550B
5 V, 3.3 V and 2.5 V UART with 16-byte FIFOs
6.5 Programmable baud rate generator
The SC16C550B supports high speed modem technologies that have increased input
data rates by employing data compression schemes. For example, a 33.6 kbit/s modem
that employs data compression may require a 115.2 kbit/s input data rate. A 128.0 kbit/s
ISDN modem that supports data compression may need an input data rate of 460.8 kbit/s.
The SC16C550B can support a standard data rate of 921.6 kbit/s.
A single baud rate generator is provided for the transmitter and receiver, allowing
independent TX/RX channel control. The programmable baud rate generator is capable of
accepting an input clock up to 48 MHz, as required for supporting a 3 Mbit/s data rate.
The SC16C550B can be congured for internal or external clock operation. For internal
clock oscillator operation, an industry standard microprocessor crystal is connected
externally between the XTAL1 and XTAL2 pins (see Figure 10). Alternatively, an external
clock can be connected to the XTAL1 pin to clock the internal baud rate generator for
standard or custom rates (see Table 6).
The generator divides the input 16
× clock by any divisor from 1 to (216 1). The
SC16C550B divides the basic crystal or external clock by 16. The frequency of the
BAUDOUT output pin is exactly 16
× (16 times) the selected baud rate
(BAUDOUT = 16
× baud rate). Customized baud rates can be achieved by selecting the
proper divisor values for the MSB and LSB sections of the baud rate generator.
Programming the baud rate generator registers DLM (MSB) and DLL (LSB) provides a
user capability for selecting the desired nal baud rate. The examples in Table 6 shows
selectable baud rates when using a 1.8432 MHz crystal.
For custom baud rates, the divisor value can be calculated using the following equation:
