Audio Interfaces
See Figure 13 for a block diagram of the audio connectivity on the OMAP4460 Pandaboard ES. In this
block diagram, the signals with a red background in the box specifying their direction are analog I/Os
while all others are 1.8V digital I/Os.
The OMAP4460 Pandaboard ES provides a stacked audio connector, which provides two 3.5mm audio
jack connections. The upper jack on this stacked connector (J16A in Figure 13 below), is connected to
FM Audio Left and Right inputs of the TWL6040 Audio Companion IC (AFML/AFMR). The lower jack
on this stacked connector (J16B in Figure 13 below) is connected to the Headset Right and Left outputs of
the TWL6040. Additionally, there is a 2 nd possible connection to the TWL6040 Auxiliary outputs
(AUXLP/AUXRP). To enable this alternate path, resistors R181 and R182 would need to be removed,
and zero ohm, 0402 resistors should be installed at locations R160 and R164.
The digital path for this audio back to the OMAP4460 processor is through the PDM interface. For
expansion purposes, the left Hands-Free speaker outputs of the TWL6040 are connected to the Expansion
Connector J6 (see Paragraph 2.17 on page 41 for further details).
The Pandaboard ES also provisions a digital PCM path for Bluetooth audio from the module to
OMAP4460 via McBSP1.
