The LTC
1569-6 is a 10th order lowpass filter featuring
linear phase and a root raised cosine amplitude response.
The high selectivity of the LTC1569-6 combined with its
linear phase in the passband makes it suitable for filtering
both in data communications and data acquisition sys-

tems.
Furthermore, its root raised cosine response offers
the optimum pulse shaping for PAM data communica-
tions. The filter attenuation is 50dB at 1.5 fCUTOFF, 60dB
at 2 fCUTOFF, and in excess of 80dB at 6 fCUTOFF. DC-
accuracy-sensitive applications benefit from the 5mV
maximum DC offset.
The LTC1569-6 sampled data filter does not require an
external clock yet its cutoff frequency can be set with a
single external resistor with a typical accuracy of 3.5% or
better. The external resistor programs an internal oscilla-
tor 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 six octaves. Alterna-
tively, the cutoff frequency can be set with an external
clock and the clock-to-cutoff frequency ratio is 64:1. The
ratio of the internal sampling rate to the filter cutoff
frequency is 128:1.
The LTC1569-6 is fully tested for a cutoff frequency of
64kHz with a single 3V supply.
The LTC1569-6 features power saving modes and it is
available in an SO-8 surface mount package.
