The LTC1068 product family consists ware for Windows . The internal sam-Frequency Linear-Phase

Introduction В® is twice the clock frequency. This
allows the frequency of input signals
to approach twice the clock frequency
before aliasing occurs. Maximum
clock frequency for LTC1068-200,
LTC1068 and LTC1068-25 is 6MHz
with В±5V supplies; that for the
LTC1068-50 is 2MHz with a single 5V
supply. For low power filter applications, the LTC1068-50 power supply
current is 4.5mA with a single 5V
supply and 2.5mA with a single 3V
supply. The LTC1068 products are
available in a 28-pin SSOP surface
mount package. The LTC1068 (the
100:1 part) is also available in a 24pin DIP package. The following four
circuits are typical examples of …

DESIGN IDEAS High Clock-to-Center Frequency Ratio
LTC1068-200 Extends Capabilities
of Switched Capacitor Highpass Filter
by Frank Cox continued on page 33 вЂ“10dB 10dB/DIV input signal too much you will also
limit the passband of the filter, and
hence its usefulness.
What makes this filter different is
the 200:1 clock-to-center frequency
ratio (CCFR) and the internal sampling scheme of the LTC1068-200.
Figure 2a shows the amplitude
response of the filter plotted against
frequency from 100Hz to 10kHz. For
comparison, Figure 2b shows the
same filter built with an LTC1068-25.
This is a 25:1 CCFR part. The 200:1
CCFR filter delivers almost 30dB more
ultimate attenuation in the stopband.
A standard amplitude vs frequency
plot of a highpass filter can be misleading because it masks some of the
aforementioned spurious signals
introduced into the passband. Figure
3a is a spectrum plot of the 200:1
filter with a single 10kHz tone on the …
