LTC1069-7  
Linear Phase  
8th Order Lowpass Filter  
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 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 filter with linear  
phase and sharper roll off than conventional Bessel filters  
can use the LTC1069-7.

DESCRIPTION  
the typical passband gain of the LTC1069-7 is equal to –1V/V.  
The LTC®1069-7 is a monolithic, clock-tunable, linear  
phase, 8th order lowpass filter. The amplitude response  
of the filter approximates a raised cosine filter with an  
alphaofone. Thegainatthecutofffrequencyis3dBand  
the attenuation at twice the cutoff frequency is 43dB. The
