Intel LXT385 Octal E1 S/H PCM Transceiver with JA
The LXT385 transceiver dissipates power in two ways:
Power dissipation of the transceiver itself.
Load power dissipation on external resistors and capacitors.
The maximum load power (current draw) for the LXT385transceiver is the sum of these two
power dissipation factors.
Table 56 lists load power consumption values. Load includes the power being dissipated in the two
RT resistors, the termination resistor, cables, and the transformer.

1. Current consumption over full range of the operating temperature and power supply voltage for the
LXT385 ransceiver. Includes all channels.
2. Power consumption includes power absorbed by the line load external to theLXT385 ransceiver
drivers.
3. Load includes the power being dissipated in the two RT resistors, the termination resistor, cables, and
transformer
