8. CONNECTORS
Table 1 lists the connectors on the CDB5343, the reference designator of each connector, the directionality, and
the associated signal.
9. JUMPER AND SWITCH SETTINGS
The user can fully configure the CDB5343 with a bank of six DIP switches (S1) and a single jumper setting on header
J4.
9.1 Jumper J4
This jumper selects the magnitude of VA, either 3.3 V or 5 V. The CS5343 is a single-supply device; there-
fore the magnitude of VA affects the full-scale analog input voltage as well as the digital I/O voltage. Digital
I/O is always fixed at VA, and the full-scale input is nominally 0.56xVA Vpp, as specified in the CS5343 data
sheet. If the user selects 5 V, the CS5343 full-scale analog input voltage is 2.82 Vpp (1 Vrms) and the digital
I/O is set to 5 V. If 3.3 V is selected, the full-scale analog input voltage is 1.86 Vpp (660 mVrms) and digital
I/O is 3.3 V.
9.2 Switch S1
Table 2 shows the available settings for S1 with the default settings.
9.2.1 CS5343
This switch configures the CS5343 for either Master Mode or Slave Mode operation. When set as clock
Master, the CS8406 must be set to “Slave” and “SCLK, LRCK” must be set to “TO HDR.” When CS5343
is configured for Slave Mode, the CS8406 must be set for Master Mode, or “SCLK, LRCK” must be set to
“FROM HDR.”
