Power Saving Considerations
Whereas the AD8158 power consumption is very low compared
to similar devices, careful control of its operating conditions can
yield further power savings. Significant power reduction can be
realized by operating the part at a lower voltage. Compared to
3.3 V operation, a supply voltage of 1.8 V can result in power
savings of ~45%. There is no performance penalty when oper-
ting at lower voltage.
A second measure is to disable transmitters when they are not
being used. This can be done on a static basis if the output is
not used or on a dynamic basis if the output does not have a
constant stream of traffic. On transmit disable (Register 0x48,
Register 0x88, Register 0xC8), both the predriver and output
switch currents are disabled. The LOS-activated squelch
disables only the output switch current, ITTO. Superior power
saving is achieved by using the TX and RX disable registers to
turn off an unused lane as opposed to relying on the AD8158
transmit squelch feature.
Because the majority of the power dissipated is in the output
stage, some of its flexibility can be used to lower the power
consumption. First, the output current and output preemphasis
settings can be programmed to the smallest amount required to
maintain BER performance. If an output circuit always has a
short length and the receiver has good sensitivity, then a lower
output current can be used.
It is also possible to lower the voltage on VTTO to lower the
power dissipation. The amount that VTTO can be lowered is
dependent on the lowest of all the output’s VOL and VCC. This
is determined by the output that is operating at the highest
output levels.
