PRINCIPLES OF OPERATION
transmit operation (continued)
receive output power amplifiers
A balanced-output amplifier is provided to allow maximum flexibility in output configuration. Either of the two
outputs can drive single-ended loads (i.e. referenced to AGND). Alternatively, the differential output can directly
drive a bridged load. The output stage is capable of driving resistive loads as low as 300
to a single-ended
level of 12 dBm, or as low as 600
in the differential mode to a level of 15 dBm.
Transmission levels are specified relative to the receive channel output under digital milliwatt conditions (i.e.
when the digital input at PCMIN is the 8-code sequence specified in CCITT recommendation G.711).
