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 reference clock of the
device is 148.5 MHz and matches the incoming signals to within 50 ppm using the UP
and DN voltage control lines to the voltage-controlled crystal oscillator (VCXO).
Table 2–25
lists the supported output standards for the SD and HD input.
