General Description
The HMC1023LP5E is a 6th order, programmable
bandwidth, fully calibrated, dual low pass filter. It
features programmable 0 or 10 dB gain and supports
arbitrary bandwidths from 5 MHz to 72 MHz. When
calibrated, the bandwidth is accurate to +/-2.5%. Built-
in filter bypass option enables wider bandwidths while
maintaining programmed gain and common mode
control settings.
Integrated ADC driver, programmable input
impedance, and adjustable output common mode
voltage from 0.9 V to 3 V with 2 Vppd signal, or lower
than 0.9 V common mode with lower signal swing
enables simple interface while achieving maximum
performance. Programmable bias settings enable
performance/power dissipation trade-off optimized for
each application.
Filter calibration is accomplished with any reference
clock rate from 20 to 80 MHz. One time programmable
(OTP) memory offers unsurpassed flexibility allowing
the user “set and forget” parameters like gain and
bandwidth setting.
Housed in a compact 5x5 mm SMT QFN package, the
HMC1023LP5E is pin and register compatible to the
existing HMC900LP5E programmable bandwidth Low
Pass Filter. It requires minimal external components
and provides a low cost alternative to more complicated
switched discrete filter architectures.
The 6th order Butterworth transfer function delivers
superior stop band rejection while maintaining both a
flat passband and minimal group delay variation.
