PIN DESCRIPTIONS
VDD
Positive Device Supply (Pin 1)
VDD is the positive supply, nominally + 5 volts.
STBY
Active–Low Standby Input (Pin 2)
A low level on the STBY pin will force the device into a
standby state. If the device is being operated in the master
mode (MSTR = 1), the WCLK internal divider can be
programmed using the DIR/DILR, and BCLK pins while
the STBY pin is active. When the device is in standby, the
DOL and DOR pins will output a 50% duty cycle data stream
that will generate a 1/2 scale analog output, when averaged
through the output filter.
DIL/WDLY
Left Channel Data/Word Clock Delay Input (Pin 3)
When the DMODE pin is low, this pin is the left channel
(MSB first) 2’s complement serial data input. When the
DMODE pin is high, this pin controls the WCLK delay. A high
level on this pin will delay the WCLK an additional clock cycle
internal to the device.
DIR/DILR
Right Channel Data/Multiplexed Left – Right Data Input
(Pin 4)
When the DMODE pin is low, this pin is the right channel
(MSB first) 2’s complement serial data input. When the
DMODE pin is high, this pin is the multiplexed left then right
channel data input. If the part is being operated in the master
mode (MSTR = 1), the WCLK internal divider can be pro-
grammed by clocking control word data onto this pin with the
BCLK pin while the device is in the standby mode (STBY
= 0).
BCLK
Bit Clock Input (Pin 5)
The BCLK pin provides the serial bit shift clock for the left
and right channel data in all modes of operation. A rising
edge on the BCLK pin shifts serial data into the device.
WCLK
Word Clock Output/Input (Pin 6)
The WCLK pin is used to latch the shifted serial data word
into the device. The MC145074 can accept an external word
clock when in the slave mode, or can use an internally
generated word clock when operating in the master mode.
When DMODE is low, left and right channel data is latched
into the device on the falling edge of WCLK. When DMODE
is high, left channel data is latched on the rising edge of
WCLK and right channel data is latched on the falling edge of
WCLK with both channel inputs being input to the modulator
on the next rising edge of WCLK. The internal divide ratio
used to generate WCLK, as well as the rising or falling edge
latching of the input data can be programmed using the DIR/
DILR and BCLK pins while the device is in the standby mode.
MSTR
Active–High Master Mode Select Input (Pin 7)
A high level on the MSTR pin will select the master mode
of operation. In the master mode, the MC145074 will
generate and output a word clock signal on the WCLK pin. A
low level on the MSTR pin will place the MC145074 in the
slave mode, and the WCLK signal must be provided by an
external source. The default master mode divide rate is
MODCLK/64.
VSS
Device Ground (Pin 8)
VSS is normally connected to ground.
DOR
Right Channel Data Output (Pin 9)
DOR is the right channel modulator data output.
DIV2
Master Clock Divide Control Input (Pin 10)
DIV2 is the Xin divide by two control pin. When cleared, the
Xin pin directly provides the modulator clock (MODCLK), and
the data output bit streams are not chopped. When this pin is
set, the Xin clock is divided by two to provide the modulator
clock and the output data bit stream is chopped at the Xin fre-
quency using an alternating 1,0 chop. The chop is used to
reduce even order distortion for a stand–alone application
without the MC145076. The reconstructed output signal will
drop 6dB due to the chopping.
Xout
Master Clock Output (Pin 11)
Xout is the inverted output signal of Xin and may be used
for a buffered clock output or for a crystal oscillator.
Xin
Master Clock Input (Pin 12)
Xin is the input clock pin for the MC145074, and may be
used with Xout as the inverter for a crystal oscillator.
DMODE
Data Mode Input (Pin 13)
A low level on the DMODE pin will select the dual data pin
mode of operation. In this mode, the serial input data is
entered on the DIR and DIL pins. A high level on the DMODE
pin selects the multiplexed mode of operation. In this mode,
the left and right channel serial input data must be multi-
plexed on the DIR/DILR pin.
RES0 and RES1
Input Data Resolution Pins (Pins 14, 15)
The RES0 and RES1 pins select the length of the serial
data word input to the MC145074. The serial input data can
be 16, 18, or 20–bits in length with the most significant bits
clocked in first. Figure 9 lists the serial interface formats.
DOL
Left Channel Data Output (Pin 16)
DOL is the left channel modulator data output.
