     * @group:       	4.1.1.1 Analog Echo Cancellation Circuit
     *
     * @description: 	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-Te/100BASE-TX mode.
