Description
Chip Enable Input. Active high. Threshold is equal to V
Gain Control Input. The voltage on this pin controls the gain on the IF VGA. The gain
control voltage range is from 0.2 V to 1.2 V and corresponds to a conversion gain range
from +25.5 dB to −18.5 dB. This is the gain to the output of the mixers (that is, IMXO and
QMXO). There is an additional 20 dB of fixed gain in the final baseband amplifiers (IAIN to
IOPP/IOPN and QAIN to QOPP/QOPN). Note that the gain control function has a negative
sense (that is, increasing voltage decreases gain).
Auxiliary Mixer Inputs. If ENVG is low, the IFIP and IFIN inputs are disabled and MXIP and
MXIN are enabled, allowing the VGA to be bypassed. The auxiliary mixer inputs are fully
differential inputs that should be ac-coupled to the signal source.
Active High VGA Enable. When ENVG is high, IFIP and IFIN inputs are enabled and MXIP
and MXIN inputs are disabled. When ENVG is low, MXIP and MXIN inputs are enabled and
IFIP and IFIN inputs are disabled.
