2.2 Jumper Options
There are various jumpers on the board that can be configured in various
ways, depending upon the user’s requirements. Their functions are briefly
presented in Table 2
− 2:
Table 2 − 2. Jumper Options
Jumper Function
W1 Selects whether U2 is either a master or a slave codec
W2 Used along with W2 for correct polarity for FSD
W3 Manages FSD from the master. Either connecting FSD to next co-
dec or providing relevant polarity.
W4 Source for INM1b
W5 Source for INM1a
W6 Coupling for OUTP1b. Either directly or via capacitor.
W7 Coupling for OUTP1a. Either directly or via capacitor.
W8 Connects analog and digital ground together
W9 Gives user the option of disconnecting the 3.3-V driver ground
from the regular analog ground
W10 Use for odd number codec channels. Isolate the data from the co-
dec not participating in the chain.
P1.9–P1.10 Last FSD in the chain must be high
P1.11–P1.12 SCL must be high
P1.13–P1.14 SDA must be high
Since the EVM contains two codecs, there a variety of options available to the
user:
-
Stand-alone slave codec
-
Single master codec
-
Master/slave cascade
Each of these options are discussed in the following sections.
2.2.1 Stand-Alone Slave
This configuration applies to EVM1 only. When a single codec is to be used
in slave mode, U2 is always the slave codec. Follow the jumper settings
detailed in Table 2
− 3 for this condition.
