Maximum total power value is specified across the full operational temperature and voltage range when CDRs are locked or a lack of input signal results in squelch being activated. If incorrect frequencies cause the CDRs to continuously attempt to lock, maximum power dissipation may reach 4.5 W. 2. Output voltage is settable in 4 discrete ranges via I2C. Default range is Range 2 (400 - 800 mV). IV.
