Functional Description: 1000Base-T Transceiver
The 1000Base-T transceiver is based-on a mixed-signal / digital signal processing (DSP) architecture, which includes
the analog front-end, digital channel equalizers, trellis encoders/decoders, echo cancellers, cross-talk cancellers,
precision clock recovery scheme, and power efficient line drivers.
The following figure shows a high-level block diagram of a single channel of the 1000Base-T transceiver for one of the
four differential pairs.

Analog Echo Cancellation Circuit
In 1000Base-T mode, the analog echo cancellation circuit helps to reduce the near-end echo. This analog hybrid circuit
relieves the burden of the ADC and the adaptive equalizer.
This circuit is disabled in 10Base-T/100Base-TX mode.
Automatic Gain Control (AGC)
In 1000Base-T mode, the automatic gain control (AGC) circuit provides initial gain adjustment to boost up the signal
level. This pre-conditioning circuit is used to improve the signal-to-noise ratio of the receive signal.
Analog-to-Digital Converter (ADC)
In 1000Base-T mode, the analog-to-digital converter (ADC) digitizes the incoming signal. ADC performance is essential
to the overall performance of the transceiver.
This circuit is disabled in 10Base-T/100Base-TX mode.
