7812UDXD Series 3G/HD Up/Down/Cross Converter with Simultaneous Dual Format Outputs and AES I/O
When a particular GPIO is configured to be a GPO, the interface shown below shall apply. The GPO is
active low with internal pull up (10k Ohm) resistors to +5V. When the output goes low, it is able to sink up
to 10mA. When high, the signal will go high (+5V). Do not draw more than 100µA from the output.
Figure 3-7 shows the circuit for the general-purpose output.

AES INPUTS

The –AES8 versions of the 7812UDXD series modules support 8x AES inputs and are interfaced using a
DB15 connector and a breakout cable. The part number for the cable is # WPAES8-BNCM-9W-6F. Two
cables (one for AES input and one for AES output) are included when the –AES8 option is ordered. The
pin-out of the DB15 connector is shown in Table 3-2. The pin-out of the breakout cable is shown in Table
3-3.
