P17 is used to connect towards the next sub board and P18 is used to connect towards the main board. These

connectors allow the AD2437 on the EVAL board to communicate to other A

rings diffuse surface mount LEDs that are activated if the bus bias is on.

Part Description

3 pole XLR receptacle

XLR cable assembly

I2C/SPI Connector ( P2 and P23)

P2 and P23 and SPI signals interfaced with AD2437 IC respectfully. They can be interfaced with external cus-

tom boards if required. The connectors are 0.1" headers. The pin out can be found in the schematic.

Sigma Studio+ ( P22)

This connector interfaces with SigmaStudio+ through the

with Total Phase Aardvark TP240141.The connector is a 0.1" header, the pinout can be found in the schematic.

4 Channel ADC Input ( P1, P9, P3, and P4)

There are four ADC channels in the AD1937 configured as two stereo pairs with differential inputs. The ADCs can

operate at a nominal sample rate of 48 kHz, 96 kHz, or 192 kHz. The ADCs include on-board digital antialiasing

filters with 79 dB stop band attenuation and linear phase response, operating at an oversampling ratio of 128 (48

kHz, 96 kHz, and 192 kHz modes). Digital outputs are supplied through two serial data output pins (one for each

stereo pair) and a common frame clock (ALRCLK) and bit clock (ABCLK). Alternatively, one of the TDM modes

can be used to access up to 16 channels on a single TDM data line.
