Common-Mode Voltage (0.5V
CC)
. This pin should be connected to ground through a capacitor.
Decouple Pin for Reference Voltage 1 (0.99V
CC
). This pin should be connected to ground through a capacitor.
Decouple Pin for Reference Voltage 2 (0.2V
CC
). This pin should be connected to ground through a capacitor.
Analog Input for the ADC.
Analog Ground for the ADC Input Signal.
Master/Slave Select. This pin is used to determine the operating mode for the serial interface. A logic ‘0’ on this pin selects the Slave
Mode. A logic ‘1’ on this pin selects the Master Mode.
(2)
Time Slot Mode Control. This pin is used to select the time slot operating mode. A logic ‘0’ on this pin disables Time Slot Mode. A
logic ‘1’ on this pin enables Time Slot Mode.
(2)
Bit Clock. This pin serves as the bit (or shift) clock for the serial interface. This pin is an input in Slave Mode and an output in Master
Mode.
(1)
Frame Sync. This pin serves as the frame synchronization clock for the serial interface. This pin is an input in Slave Mode and an
output in Master Mode.
(1)
Serial Data Input. This pin is used to write 16-bit data to the DAC.
(1)
Serial Data Output. The ADC outputs 16-bit data on this pin.
(3)
Frame Sync Output. Active only when Time Slot Mode is enabled. This pin is set to a high impedance state when Time Slot mode
is disabled (TSC = 0).
Digital Power Supply. Used to power the digital section of the ADC and DAC, as well as the serial interface and mode control logic.
This pin is not internally connected to V
CC
.
Digital Ground. Internally connected through the substrate to analog ground.
System Clock Input/Output. This pin is a system clock output when using the crystal oscillator or XTI as the system clock input; when
XTI is connected to ground, this pin is a system clock input.
(1)
Crystal Oscillator Output.
Crystal Oscillator Input or an External System Clock Input.
High-Pass Filter Disable. When this pin is set to a logic ‘1’, the HPF function in the ADC is disabled.
(2)
ADC-to-DAC Loop-Back Control. When this pin is set to logic ‘1’, the ADC data is fed to the DAC input.
(2)
Power Down and Reset Control. When this pin is logic ‘0’, Power-Down Mode is enabled. The PCM3500 is reset on the rising edge
of this signal.
(2)
Analog Ground for the DAC Output Signal.
Analog Output from the DAC Output Filter.
Analog Ground. This is the ground for the internal analog circuitry.
Analog Power Supply. Used to power the analog circuitry of the ADC and DAC.
