LTC1569-7  
Linear Phase, DC Accurate,  
Tunable, 10th Order Lowpass Filter  
Furthermore, its root raised cosine response offers the  
optimum pulse shaping for PAM data communications.  
The filter attenuation is 50dB at 1.5 • fCUTOFF, 60dB at 2 •

10th Order, Linear Phase Filter in an SO-8  
The LTC1569-7 is the first sampled data filter which does  
notrequireanexternalclockyetitscutofffrequencycanbe  
set with a single external resistor with a typical accuracy  
of 3.5% or better. The external resistor programs an  
internal oscillator whose frequency is divided by either 1,  
4 or 16 prior to being applied to the filter network. Pin 5  
determines the divider setting. Thus, up to three cutoff  
frequencies can be obtained for each external resistor  
value. Using various resistor values and divider settings,  
the cutoff frequency can be programmed over a range of  
seven octaves. Alternatively, the cutoff frequency can be  
set with an external clock and the clock-to-cutoff fre-  
quency ratio is 32:1. The ratio of the internal sampling rate  
to the filter cutoff frequency is 64:1.

DESCRIPTIO  
The LTC1569-7 is fully tested for a cutoff frequency of  
256kHz/128kHz with single 5V/3V supply although up to  
300kHz cutoff frequencies can be obtained.  
The LTC®1569-7 is a 10th order lowpass filter featuring  
linear phase and a root raised cosine amplitude response.  
The high selectivity of the LTC1569-7 combined with its  
linear phase in the passband makes it suitable for filtering  
bothindatacommunicationsanddataacquisitionsytems.  
The LTC1569-7 features power savings modes and it is  
available in an SO-8 surface mount package.
