This is defined as the amplitude of the clock frequency  
appearing at the output pins of the device, Figure 2. Clock  
feedthroughismeasuredwithallthreesidesoftheLTC1061  
connected as filters. The clock feedthrough mainly de-  
pends on the magnitude of the power supplies and it is  
independent from the input clock levels, clock frequency  
and modes of operation.

Operating with a Single 5V Supply.  
50/100/Hold (Pin 7)  
B = 10mV/DIV  
By tying Pin 7 to V+, the filter operates with a clock-to-  
center frequency internally set at 50:1. When Pin 7 is at  
mid-supplies, the filter operates with a 100:1 clock-to-  
center frequency ratio. Table 1 shows the allowable varia-  
tion of the potential at Pin 7 when the 100:1 mode is  
sought.

with ±5V Supplies. Top Trace is the Input Clock Swinging 0V to  
5V and Bottom Trace is One of the Lowpass Outputs with Zero or  
DC Input Signals.  
When Pin 7 is shorted to the negative supply pin, the filter  
operation is stopped and the bandpass and lowpass  
output act as a sample-and-hold circuit holding the last  
sample of the input voltage. The hold step is around 2mV  
and the droop rate is 150µV/sec.
