Typical value for resistors = 2.2 kΩ.
Lower resistor values can be used down to 500 Ω to obtain higher sampling frequencies in the 150 MSPS range (limited by t_d and t_HD timings). In this
configuration a DC shift of the ECL output levels V_OL and V_OH will occur.
V_RB, V_RT and V_M are decoupled to AGND.
Analog, digital and output supplies should be separated and decoupled.
The external voltage regulator must be constructed in such a way that a good supply voltage ripple rejection is achieved with respect to the LSB value.
