PRINCIPLES OF OPERATION
receive output power amplifiers
A balanced-output amplifier is provided to allow maximum flexibility in output configuration. Either of the two
outputs can be used single ended (i.e., referenced to ANLG GND) to drive single-ended loads. Alternatively,
the differential output directly drives a bridged load. The output stage is capable of driving loads as low as 300-
single-ended to a level of 12 dBm or 600
differentially to a level of 15 dBm.
The receive channel transmission level may be adjusted between specified limits by manipulation of the GSR
input. GSR is internally connected to an analog gain-setting network. When GSR is connected to PWRO–, the
receive level is maximum. When GSR is connected to PWRO+, the level is minimum. The output transmission
level is adjusted between 0 and –12 dB as GSR is adjusted (with an adjustable resistor) between PWRO+ and
PWRO–.
Transmission levels are specified relative to the receive channel output under digital milliwatt conditions
(i.e., when the digital input at PCM IN is the eight-code sequence specified in CCITT recommendation G.711).
