Note 1. Output level set by RxXLEVEL external resistor. For 10GE module application, amplitude will meet the XAUI near-end template
specified in IEEE 802.3. For XFP line card application, output level can be adjusted down to 300mVpp differential for minimum power.
Note 2. For 625MHz < freq < 3.125GHz, S22D = -10 + 10log(freq/625) dB
