DESCRIPTION
The PCM3501 is a low cost, 16-bit CODEC designed
for modem Analog Front End (AFE) and speech pro-
cessing applications. The PCM3500’s low power op-
eration from +2.7V to +3.6V power supplies, along
with an integrated power-down mode, make it ideal for
portable applications.
The PCM3501 integrates all of the functions needed for
a modem or voice CODEC, including delta-sigma
digital-to-analog and analog-to-digital converters, in-
put anti-aliasing filter, digital high-pass filter for DC
blocking, and an output low-pass filter. The synchro-
nous serial interface provides for a simple, or glue-free
interface to popular DSP and RISC processors. The
serial interface also supports Time Division Multiplex-
ing (TDM), allowing up to four CODECs to share a
single 4-wire serial bus.

PIN ASSIGNMENTS
PIN NAME I/O DESCRIPTION
1 VCOM OUT Common-Mode Voltage (0.5VCC). This pin should be connected to ground through a capacitor.
2
VREF1
— Decouple Pin for Reference Voltage 1 (0.99VCC). This pin should be connected to ground through a capacitor.
3
VREF2
— Decouple Pin for Reference Voltage 2 (0.2VCC). This pin should be connected to ground through a capacitor.
4 VIN+ IN Non-Inverting input to on-chip AFE.
5 VIN– IN Inverting input to on-chip AFE.
6 M/S IN 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)
7
TSC
IN 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)
8
BCK
I/O 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)
9 FS I/O 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)
10 DIN IN Serial Data Input. This pin is used to write 16-bit data to the DAC.(1)
11 DOUT OUT Serial Data Output. The ADC outputs 16-bit data on this pin.(3)
12 FSO OUT 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).
13 VDD — 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 VCC.
14 DGND — Digital Ground. Internally connected through the substrate to analog ground.
15 SCKIO I/O 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)
16 XTO OUT Crystal Oscillator Output.
17 XTI IN Crystal Oscillator Input or an External System Clock Input.
18 HPFD IN High-Pass Filter Disable. When this pin is set to a logic ‘1’, the HPF function in the ADC is disabled.(2)
19 LOOP IN ADC-to-DAC Loop-Back Control. When this pin is set to logic ‘1’, the ADC data is fed to the DAC input.(2)
20 PDWN IN 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)
21 VOUT– OUT Inverting output.
22 VOUT+ OUT Non-inverting output.
23 AGND — Analog Ground. This is the ground for the internal analog circuitry.
24 VCC — Analog Power Supply. Used to power the analog circuitry of the ADC and DAC.
NOTES: (1) Schmitt-Trigger input. (2) Schmitt-Trigger input with an internal pull-down resistor. (3) Tri-state output in Time Slot Mode.
