EQCO30T5.2
1.2 Circuit Operation
Figure 1-3 is a block diagram of the EQCO30T5,
showing electrical connections. The input pre-driver
brings the input signal to a digital signal, with or without
the use of input trace equalization. The active splitter/
combiner/driver launches the digital signal in the cable,
with an amplitude determined by the external resistor
connected to R_ref and with an edge rate for SD or 3G/
HD-SDI depending on the SD/HDB signal. It also splits
the incoming signal towards the LF receiver to provide
the 5 Mbps LF_out signal.
