PCM1840 Evaluation Module
1 Introduction
The PCM1840EVM is an evaluation module (EVM) designed to demonstrate the performance and
functionality of the PCM1840 device. The PCM1840 is a high-performance audio analog-to-digital
converter (ADC) that is configured through logic-level mode selection pins and does not require a digital
interface such as I2C or SPI to configure registers. As such, no software is necessary to interface with the
EVM. The EVM is powered with a single 5-V supply. Access to the converter output is provided on the
audio serial interface in I2S, LJ, or TDM format.
2 Power Supply
The PCM1840EVM can be powered with a single 5-V power supply connected to J6. Onboard low dropout
regulators convert the 5-V supply to the 3.3-V and 1.8-V rails used by the ADC. The analog supply,
AVDD, is fixed at 3.3 V. The digital supply, IOVDD, can be set to either 1.8 V or 3.3 V with J5. It is also
possible to power the ADC directly by removing J9 and J5 and applying a voltage directly to the AVDD
and IOVDD test points. Note that if this is done, it is important to keep J10 populated (or ensure there is a
path between the pins if the supply current is being monitored) as this jumper connects the applied IOVDD
to the mode selection pins and other circuitry that relies on IOVDD. If external supplies are used, there is
an onboard voltage supervisor, U3, that will hold the ADC in shutdown until both AVDD and IOVDD have
reached their respective threshold voltages. The shutdown thresholds for the supply voltages can be
adjusted as shown in Equation 1 and Equation 2. The supervisor can also be removed from the shutdown
logic by depopulating R5. For more information on the reset supervisor, see the TPS37xx Dual-Channel,
Low-Power, High-Accuracy Voltage Detectors Data Sheet.

3 Hardware Configuration
The format of the audio data and the operating mode of the ADC are controlled by the following pins:
MD0, MD1, MSZ, FMT0, and FMT1. These signals are referenced to IOVDD and can be set to high (1) or
low (0). If no shunt is installed, then a 10-kΩpulldown resistor will set the pin low so that the ADC remains
in a defined state. Table 1 shows the header numbers and their pin functions and Table 2 shows the
possible modes and output formats. The MSZ pin selects whether the device is a master or a slave on the
audio bus. When MSZ is pulled high, the device is in slave mode and MD1 becomes an input for MCLK. A
shunt connecting J19 to the center pin of J18 will route the MCLK signal provided on J8 to the MD1 pin on
the ADC to allow for easy interfacing with audio measurement equipment.

3.1 PCM1840EVM Inputs
The PCM1840 device is intended to be driven with differential line inputs or microphone inputs. Each of
the inputs has a 1-µF AC coupling film capacitor. Coupled with the 2.5-kΩinput impedance, this sets the
high pass filter cutoff frequency at approximately 63 Hz. This can be adjusted by replacing the input AC
coupling capacitors on the EVM if necessary. Figure 1 shows the architecture of the inputs to the
evaluation module. The EVM supports a differential full scale input range of 2 VRMS with an AVDD of 3.3 V.
Figure 1. PCM1840EVM Input Architecture
3.1.1 Line Inputs
For the line input configuration, shown in Figure 2, the PCM1840 captures the audio signal provided
through terminals J1 (IN1), J2 (IN2), J3 (IN3), and J4 (IN4). The input accepted in this mode is a
differential, 2 VRMS, full-scale audio signal. Single-ended inputs are not supported by the PCM1840 device
and the inputs should be AC coupled.

3.1.2 Onboard Microphone Input
For the onboard microphone input configuration (shown in Figure 3), the PCM1840EVM records the audio
captured from the microphone located on the bottom-left edge of the board. MICBIAS is used to power the
onboard microphone through J14. J15, and J16 must be installed to connect the microphone output to the
ADC inputs. There must not be any connections to J1 during onboard microphone use to preserve the
performance of the microphone.
