Description
The SKY73201-364LF & SKY73202-364LF are high-performance,
programmable, monolithic, clock-referenced low-pass filters.
They are configured as a 6th order Butterworth to provide
extremely high stop-band isolation while maximizing pass-band
flatness and minimizing group delay distortion. The corner
frequency is programmable, via the 3-wire Serial Peripheral
Interface (SPI), in steps, from 1–28 MHz, when a 20 MHz or
40 MHz reference is used. Nearly ideal Butterworth performance
is maintained over temperature and process via a proprietary
internal calibration circuit which derives its timing accuracy from
the reference clock. Nominal reference clock frequencies of
20 MHz or 40 MHz are recommended to meet the specifications
outlined in this data sheet but other reference clock frequencies
can be accommodated with appropriate changes to the
control register settings. The corner frequency range can be
extended beyond 28 MHz by the use of alternate reference clock
frequencies and modified control register settings. Please contact
Skyworks Solutions applications engineering for assistance with
your requirements.
Additionally, the SKY73201-364LF & SKY73202-364LF offer excel-
lent linearity and input noise level (83 dB SNR at 1 MHz corner
setting), making them suitable for extremely high dynamic range
applications such as adjacent channel rejection filters in direct con-
version receivers. The I/O interface is fully differential, but may also
be used single-ended, and on-chip input/output drivers allow easy
integration between modern system components such as mixers,
data converters, and variable gain amplifiers.
The dual configuration of SKY73202 offers the convenience of having
two channels (such as the I and Q in vector demodulation) with
closely matched characteristics that track each other. Both filters
are programmed to the same settings by the common SPI interface.

Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION: A lthough this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all
times from ESD. Static charges may easily produce
potentials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.

1. Gain in dBV = 20log10 (Vout_rms/Vin_rms), independent of impedance.
2. Group delay scales inverse-linearly with cutoff frequency; average group delay variation = 350 ns/Cutoff_in_MHz
3. A 50 + 50 W load may be driven but voltage gain may be reduced and signal-linearity may be affected. The overall filter shape should be preserved.
4. The reference clock signal must have a duty cycle of 50%.
