6.5.6. SDI Video Input/Output Ports

The Arria® 10 GX FPGA development board includes a SDI video port, which consists of a M23428G-33 cable driver and a M23544G-14 cable equalizer. The PHY devices from Macom interface to single-ended SMB connectors.

The cable driver supports operation from 125 Mbps to 11.88 Gbps. Control signals are allowed for SD and HD modes selections, as well as device enable. The device can be clocked by the 148.5 MHz voltage-controlled crystal oscillator (VCXO) and matched to incoming signals within 50 ppm using the UP and DN voltage control lines to the VCXO.
