LTC1064-7  
Linear Phase, 8th Order  
Lowpass Filter  
U
FEATURES  
DESCRIPTIO  
The LTC®1064-7 is a clock-tunable monolithic 8th order  
lowpass filter with linear passband phase and flat group  
delay. The amplitude response approximates a maximally  
flat passband while it exhibits steeper roll-off than an  
equivalent8thorderBesselfilter. Forinstance, attwicethe  
cutoff frequency the filter attains 34dB attenuation (vs  
12dBforBessel),whileatthreetimesthecutofffrequency,  
the filter attains 68dB attenuation (vs 30dB for Bessel).  
The cutoff frequency of the LTC1064-7 is tuned via an  
external TTL or CMOS clock.  
Steeper Roll-Off Than 8th Order Bessel Filters  
fCUTOFF up to 100kHz  
Phase Equalized Filter in 14-Pin Package  
Phase and Group Delay Response Fully Tested  
Transient Response Exhibits 5% Overshoot and  
No Ringing  
Wide Dynamic Range  
72dB THD or Better Throughout a 50kHz Passband  
No External Components Needed  
Available in 14-Pin DIP and 16-Pin SO Wide  
Packages  
The LTC1064-7 features wide dynamic range. With single  
5V supply, the S/N + THD is 76dB. Optimum 92dB S/N is  
obtained with ±7.5V supplies.  
U
APPLICATIO S  
The clock-to-cutoff frequency ratio of the LTC1064-7 can  
be set to 50:1 (Pin 10 to V+) or 100:1 (Pin 10 to V).  
Data Communication Filters  
Time Delay Networks  
When the filter operates at clock-to-cutoff frequency ratio  
of 50:1, the input is double-sampled to lower the risk of  
aliasing.  
Phase-Matched Filters  
The LTC1064-7 is pin-compatible with the LTC1064-X  
series, LTC1164-7 and LTC1264-7.
