Clock feedthrough is measured with all three sides of the LTC1061 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. The Table 2 illustrates the typical clock feedthrough num- bers for various power supplies. 50/100/Hold (Pin 7) 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. 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 150 µV/sec. Table 1 TOTAL POWER SUPPLY VOLTAGE RANGE OF PIN 7 (V) FOR 100:1 OPERATION (V) 5 2.5 ± 0.5 10 5 ±1 15 7.5 ±1.5 Figure 2.
