11 / 30 page LTC1068 Series 11 1068fc PIN FUNCTIONS BLOCK DIAGRAM path. A 200Ω resistor between clock source and Pin 11 will slow down the rise and fall times of the clock to further reduce charge coupling (Figures 1 and 2). Output Pins Each 2nd order section of an LTC1068 device has three outputs that typically source 17mA and sink 6mA. Driv- ing coaxial cables or resistive loads less than 20k will degrade the total harmonic distortion performance of any filter design. When evaluating the distortion or noise performance of a particular filter design implemented with a LTC1068 device, the final output of the filter should be buffered with a wideband, noninverting high slew rate amplifier (Figure 3). Inverting Input Pins These pins are the inverting inputs of internal op amps and are susceptible to stray capacitive coupling from low impedance signal outputs and power supply lines. In a printed circuit layout any signal trace, clock source trace or power supply trace should be at least 0.1 inches away from any inverting input pins Summing Input Pins These are voltage input pins. If used, they should be driven with a source impedance below 5k. When they are not used, they should be tied to the analog ground pin. The summing pin connections determine the circuit to- pology (mode) of each 2nd order section. Please refer to Modes of Operation. Figure 3.
