Pin Description Table (Continued)
The EV10AS150A is a 10-bit 2.5 Gsps ADC combined with a 1:4 demultiplexer (DMUX) allowing to lower
the output Data stream (10-bit data and one out-of-range bit) by a selectable factor of 2 or 4. (Please
note that for maximal operating speed, the DMUX has to be used in 1:4 mode).
The ADC works in fully differential mode from analog input up to digital outputs. The ADC differential
Analog Inputs and Clock Inputs are on chip 100Ω terminated.
The ADC analog input can be driven in either single ended or differential configuration without significant
impact on dynamic performances (SFDR), but slight degradation on THD since the weighting of second
and third harmonics are similar in single-ended.
The output Data clock and Digital output data are LVDS logic compatible, and should be 100Ω differen-
tially terminated (2nH // 2 pF maximum output loading parasitics).
