2.5 Test Point connector

VOCM_ADJ: This connector connects to the VOCM_ADJ pin of the device and is used to set the output common mode of the VGA. If it is left floating, the resistive divider formed by R35 and R40 biases the VOCM_ADJ pin to the mid-supply voltage of the VGA

Gain_ADJ: This connector is used to set the gain adjust voltage of the VGA. By default, resistor R3 is populated, and the gain adjustment voltage is determined by the position of potentiometer R2. If the gain needs to be set using an external voltage, remove R3 and apply the desired voltage at this Gain_ADJ test point connector.

VREF: This connector is used to externally set a 0.5V reference voltage for the device, which is particularly important for applications requiring high gain accuracy. The voltage at the VREF pin can also be configured using an onboard external reference, REF35. To enable this, short R43 and R41. If left unconnected, the internal reference of the VGA will provide the required voltage for proper device operation.
