information.

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.

f For more information about the application circuit of the cable driver, refer to the

cable driver data sheet in www.national.com.

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.
