SDI Video Output/Input

The SDI video port consists of a LMH0303 cable driver and a LMH0384 cable
equalizer. The PHY devices from National Semiconductor interface to single-ended
75-

Ω SMB connectors.

The cable driver supports operation at 270 Mbit standard definition (SD), 1.5 Gbit
high definition (HD), and 2.97 Gbit dual-link HD modes. 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.

Table 2–36

lists the supported output standards for the SD and HD input.

Table 2–37

summarizes the SDI video output interface pin assignments, signal names,

and functions.

The cable equalizer supports operation at 270 Mbit SD, 1.5 Gbit HD, and 2.97 Gbit
dual-link HD modes. Control signals are allowed for bypassing or disabling the
device, as well as a carrier detect or auto-mute signal interface.
