4.2.1.5. Voltage Supervision And Other Functions
CLKI
IN
This is the clock input of the MAS 3504D. CLKI should
be a buffered output of a crystal oscillator. Standard
clock frequency is 18.432 MHz.
CLKO
OUT
This pin has no function.
PUP
OUT
The PUP
output indicates that the power supply volt-
age exceeds its minimal level (software adjustable).
WSEN
IN
WSEN enables DSP operation and switches on the
DC/DC-converter.
WRDY
OUT
WRDY has
two functions depending on the state of the
WSEN signal.
If WSEN =
’
0
’
, it indicates that a valid clock has been
recognized at the CLKI clock input.
If WSEN =
’
1
’
, the WRDY output will be set to
‘
0
’
until
the internal clock synthesizer has locked to the incom-
ing audio data stream, and thus, the CLKO clock out-
put signal is valid.
4.2.1.6. Serial Input Interface
SID
SII
SIC
IN
IN
IN
Data, Frame Indication, and Clock line of the serial
input interface. The SII indicates whether the left or the
right audio sample is transmitted.
4.2.1.7. Serial Output Interface
SOD
SOI
SOC
OUT
OUT
OUT
Data, Frame Indication, and Clock line of the serial
output interface. The SOI indicates whether the left or
the right audio sample is transmitted.
4.2.1.8. Miscellaneous
POR
IN
The Power On Reset pin is used to reset the digital
parts of the MAS 3504D. POR is a low active signal.
TE
IN
The TE pin is for production test only and must be con-
nected with VSS in all applications.
