DESCRIPTION
Dual Adjustable
Lowpass Filter
The LTC6603 is a dual, matched, programmable lowpass
lter for communications receivers and transmitters. The
selectivity of the LTC6603, combined with its linear phase,
phase matching and dynamic range, make it suitable for
ltering in many communications systems. With 1.5°
phase matching between channels, the LTC6603 can be
used in applications requiring pairs of matched lters,
such as transceiver I and Q channels. Furthermore, the
differential inputs and outputs provide a simple interface
for most communications systems.
The sampled data lter does not require an external clock
yet its cutoff frequency can be set with a single external
resistor with an accuracy of 3.5% or better. The external
resistor programs an internal oscillator whose frequency
is divided prior to being applied to the lter networks.
This allows up to three cutoff frequencies that can be
obtained for each external resistor value, allowing the
cutoff frequency to be programmed over a range of more
than six octaves. Alternatively, the cutoff frequency can
be set with an external clock. The lter gain can also be
programmed to 1, 2, 4 or 16.
The LTC6603 features a low power shutdown mode that
can be programmed through the serial interface and is
available in a 24-pin 4mm
× 4mm QFN package.
