Non-Demultiplexed DIV1 ModeThe MAX108 may be operated at up to 750Msps innon-demultiplexed DIV1 mode (Table 2). In this mode,the internal demultiplexe

MAX108Decimation DIV4 ModeThe MAX108 also offers a special decimated, demulti-plexed output (Figure 8) that discards every other inputsample and outpu

In a typical single-ended configuration, the analoginput signal (Figure 10a) enters the T/H amplifier stageat the in-phase input (VIN+), while the inv

MAX108Offset AdjustThe MAX108 provides a control input (VOSADJ) to com-pensate for system offsets. The offset adjust input is aself-biased voltage div

formance specifications are determined by a single-ended clock drive of +4dBm (500mV clock signalamplitude). To avoid saturation of the input amplifie
