filter’sDCoutputoffset(Figure1). RIN should, however, be Clock Output Pin (Pin 4, N Package)  
limited to a maximum value (Table 1), otherwise the filter’s  
passband flatness will be affected. Refer to the Applica-  
tions Information section for more details.  
Any external clock applied to the clock input pin appears  
at the clock output pin. The duty cycle of the clock output  
equals the duty cycle of the external clock applied to the  
clock input pin. The clock output pin swings to the power  
supply rails. When the LTC1063 is used in a self-clocking  
mode, the clock of the internal oscillator appears at the  
clock output pin with a 30% duty cycle. The clock output  
pin can be used to drive other LTC1063s or other ICs. The  
maximum capacitance, CL(MAX), the clock output pin can  
drive is illustrated in Figure 3.

Pin 7 is the filter output. This pin can typically source over  
20mA and sink 2mA. Pin 7 should not drive long coax  
cables, otherwise the filter’s total harmonic distortion will  
degrade.

TEST CIRCUIT  
An external clock when applied to pin 5 tunes the filter  
cutoff frequency. The clock-to-cutoff frequency ratio is  
100:1. The high (VHIGH) and low (VLOW) clock logic  
threshold levels are illustrated in Table 2. Square wave  
clockswithdutycyclesbetween30%and50%arestrongly  
recommended. Sinewave clocks are not recommended.
