4 / 8 page  AD9901 REV. B –4– TTL/CMOS MODE FUNCTIONAL PIN DESCRIPTIONS GROUND Ground connections for AD9901. Connect all grounds together and to low impedance ground plane as close to the device as possible. +VS Positive supply connection; nominally +5.0 V for TTL operation. BIAS Connect to +VS (+5 V) for TTL operation. VCO INPUT TTL compatible input; normally connected to the VCO output signal. VCO INPUT and REFERENCE INPUT are equivalent to one another. OUTPUT The noninverted output. In TTL/CMOS mode, the output swing is approximately +3.2 V to +5 V. RSET External RSET connection. The current through the RSET resistor is equal to the maxi- mum full-scale output current. RSET should be connected to ground through an external resistor in TTL mode. ISET = 0.47 V/RSET = ILOAD (max). OUTPUT The inverted output. In TTL/CMOS mode, the output swing is approximately +3.2 V to +5 V. REFERENCE TTL compatible input, normally connected INPUT to the reference input signal. The VCO INPUT and the REFERENCE INPUT are equivalent. REG RSET AD9901 R1 OUTPUT R2 +VS +VS REFERENCE OUTPUT OUTPUT +VS VCO INPUT BIAS +VS +VS R3 Figure 1. TTL Mode (Based on DIP Pinouts) ECL MODE FUNCTIONAL PIN DESCRIPTIONS –VS Negative supply connection, nominally –5.2 V for ECL operation. BIAS Connect to –5.2 V for ECL operation. VCO INPUT Inverted side of ECL compatible differential input, normally connected to the VCO output signal. VCO INPUT Noninverted side of ECL-compatible differential input, normally connected to the VCO output signal. OUTPUT The noninverted output. In ECL mode, the output swing is approximately 0 V to –1.8 V. GROUND Ground connections for AD9901. Connect all grounds together and to low-impedance ground plane as close to the device as possible. RSET External RSET connection. The current through the RSET resistor is equal to the maxi- mum full-scale output current. RSET should be connected to –VS through an external resistor in ECL mode. ISET = 0.47 V/RSET = ILOAD (max). OUTPUT The inverted output. In ECL mode, the out- put swing is approximately 0 V to –1.8 V. REFERENCE Noninverted side of ECL-compatible INPUT differential input, normally connected to the reference input signal. The VCO INPUT and the REFERENCE INPUT are equivalent to one another. REFERENCE Inverted side of ECL-compatible differential INPUT input, normally connected to the reference input signal. The VCO INPUT and the REFERENCE INPUT are equivalent.
