X: do not care
S1, S2: user-programmable bit to program the outputs S1 and S2. In
the example, S1 is set active, and S2 is inactive.
S0: IrDA pulse select
S0 = (1): 1.627 s output
S0 = (0): 3/16 bit time pulses, not recommended
B0 to B3: baud rate select words according to the following table
below.
Notes
Bold: See example
IrDA standard only supports 2.4 kbit/s, 9.6 kbit/s, 19.2 kbit/s,
57.6 kbit/s, and 115.2 kbit/s (3.6864 MHz clock). Doubling the baud
rates is permissible by doubling the clock frequency.
In figure 2 the programming sequence is shown for a bit rate
of 12.8 kbit/s.
Fig. 2 - Programming sequence for setting the endec to a bit rate
of 12.8 kbit/s. After setting BR/D high (Ch1), the programming
sequence with the control byte (Ch2) is applied to TD_232, pin 4.
Fig. 3 - Programming sequence for setting the endec to a bit rate of
12.8 kbit/s as in figure 2 but with a 3/16 bit pulse duration (S0 = “0”).
When correctly programmed, the endec shortens the pulse
to be transmitted from the full bit duration to either 3/16 of the
bit length or to 1.627 s (which is 3/16 of the 115.2 kbit/s bit
duration).
For
power
saving,
the
short
pulse
is
recommended.
The received optical pulse shows in case of most of the
Vishay SIR transceivers, constant pulse duration. The endec
stretches that to the correct bit time according the bit rate
setting. This is shown in the following chapters.
