Offset Adjust
The MAX106 provides an analog input (VOSADJ) to com-
pensate for system offsets. The offset adjust input is a
self-biased voltage divider from the internal +2.5V preci-
sion reference. The nominal open-circuit voltage is one-
half the reference voltage. With an input resistance of
typically 25k
, this pin may be driven by an external
10k
potentiometer (Figure 11) connected between
REFOUT and GNDI to correct for offset errors. This con-
trol provides a typical ±5.5LSB offset adjustment range.
Clock Operation
The MAX106 clock inputs are designed for either sin-
gle-ended or differential operation (Figure 12) with flexi-
ble input drive requirements. Each clock input is
terminated with an on-chip, laser-trimmed 50
resistor
to CLKCOM (clock-termination return). The CLKCOM
termination voltage can be connected anywhere
between ground and -2V for compatibility with standard
ECL drive levels.
The clock inputs are internally buffered with a preampli-
fier to ensure proper operation of the data converter,
even with small-amplitude sine-wave sources. The
MAX106 was designed for single-ended, low-phase-
noise sine-wave clock signals with as little as 100mV
amplitude (-10dBm). This eliminates the need for an
external ECL clock buffer and its added jitter.
Single-Ended Clock Inputs (Sine-Wave Drive)
Excellent performance is obtained by AC- or DC-cou-
pling a low-phase-noise sine-wave source into a single
clock input (Figure 13a, Table 5). For proper DC bal-
ance, the undriven clock input should be externally
50
reverse-terminated to GNDI.
