CH1_EQ1. Configuration pin used to control Rx EQ level for RX1P/N. The state

of this pin is sampled after the rising edge of EN. Refer to Figure 2 for details of

timing. This pin along with CH1_EQ2 allows for up to 16 equalization settings.

EN. Places TUSB1002A into shutdown mode when asserted low. Normal

operation when pin is asserted high. When in shutdown, TUSB1002A’s receiver

terminations will be high impedance and tx/rx channels will be disabled.
