LTC1069-7
Linear Phase
8th Order Lowpass Filter
FEATURES n 8th Order, Linear Phase Filter in SO-8 Package
Raised Cosine Amplitude Response
– 43dB Attenuation at 2× fCUTOFF
Wideband Noise: 140ОјVRMS
Operates from Single 5V Supply to
В±5V Power Supplies
Clock-Tunable to 200kHz with В±5V Supplies
Clock-Tunable to 120kHz with Single 5V Supply APPLICATIONS n Digital Communication Filter
Antialiasing Filter with Linear Phase
Smoothing Filters cutoff frequency of the LTC1069-7 is set by an external
clock and is equal to the clock frequency divided by 25.
The ratio of the internal sampling frequency to the cutoff
frequency is 50:1 that is, the input signal is sampled
twice per clock cycle to lower the risk of aliasing. The
LTC1069-7 can be operated from a single 5V supply up
to dual В±5V supplies.
The gain and phase response of the LTC1069-7 can be
used in digital communication systems where pulse
shaping and channel bandwidth limiting must be carried
out. Any system that requires an analog п¬Ѓlter with linear …
