TTSV02622 STS-24 Backplane Transceiver
LVDS I/O
LVDS Receiver Buffer Capabilities
A disabled or unpowered LVDS receiver can withstand a driving LVDS transmitter over the full range of driver oper-
ating range, for an unlimited period of time, without being damaged. Table 16 illustrates LVDS driver dc data,
Table 17 the ac data, and Table 14 on page 52 and Table 15 on page 52 the LVDS receiver data.
