Digital Internal Function
The IP1001 integrates all necessary function blocks to achieve the communication ability over CAT5
unshielded twisted pair cables. These function blocks include analog blocks and digital blocks.
Analog function blocks includes analog to digital converter (ADC), digital to analog converter (DAC), active
hybrid, and high-speed 1.25GHz transmitter/receiver. Digital function blocks include digital adaptive
feed-forward equalizer (FFE), decision-feedback equalizer (DFE), echo canceller (EC), near-end-cross-talk
canceller, baseline wander canceller, and digital phase lock-loop (DPLL). Some other encoding/decoding
blocks are also necessary in the transmission/receiving data path.

IEEE802.3 1000BASE_T Test mode
IP1001 supports four test modes for 1000BASE_T defined in IEEE802.3 clause 40.6. User can force IP1001
to be in test mode to characterize its waveform, jitter, and distortion by programming MII register 9[15:13].
