Performance Characteristics
Maximum data rate: 3.0 Gb/s for 3G, 1.5 Gb/s for HD, and 540 Mbps for SD
Minimum Data Rate : 270Mbps for 3G/s circuit boards and 3.072 Mbps for HD and
SD circuit boards.
Signal Standards: SMPTE 292M-1998,

(Output rise and fall
times correspond to SMPTE 292M).
The HO-3G conforms to SMPTE 259M (270 Mb/S), 292M
(1.5Gb/S) and 424M (3Gb/S). The output rise and fall times
adjust according to the detected data-rate.
Equalization: HI-3G Input board: For SD operation, equalization is automatic
up to 380 meters using Belden 8281 (or an equivalent coax
cable) and 500 meters using Belden 1694A. For HD operation,
equalization is automatic up to 160 meters of Belden 1694A or
an equivalent coax cable. For 3Gp/s operation, equalization is
automatic up to 140 meters of Belden 1694A, when installed in
a Trinix
