_______________________________________________________________________________________
_______________ Detailed Description
The block diagram in Figure 1 shows the MAX3840
architecture. The SELA_ and SELB_ pins control the rout-
ing of the signals through the crosspoint switch. Each
output of the crosspoint switch drives a CML output dri-
ver. Each of the outputs, DOA_ and DOB_, is enabled or
disabled by the respective ENA_ and ENB_ pins.
CML Inputs and Outputs
CML is used to simplify high-speed interfacing. On-
chip input and output terminations minimize the number
of external components required while improving signal
integrity. The CML output signal swing is small, result-
ing in lower power consumption. The internal 50
Ω input
and output terminations minimize reflections and elimi-
nate the need for external terminations.
