HMC1023LP5E v01.0113 72 MHz DUAL PROGRAMMABLE LOW PASS FILTER WITH DRIVER Typical Applications Features The HMC1023LP5E is ideal for: Low Noise Figure: 10 dB High linearity: Baseband filtering before or after data converters In-Band Output IP3 > +30 dBm for point-to-point fixed wireless and cellular In-Band Output IP2 > +60 dBm infrastructure transceivers Pre-programmed and/or Programmable Bandwidth: Software defined radio applications 5 MHz to 72 MHz. (Please see HMC1023LP5E Anti-aliasing and reconstruction filters Ordering Information) Test and measurement equipment Exceptional 3 dB Bandwidth Accuracy: 2.5% Programmable Gain: 0 or 10 dB ADC driver applications Integrated ADC Driver Amplifier th 6 order Butterworth Magnitude & Phase Response Automatic Filter Calibration Externally Controlled Common Mode Output Level Filter Bypass Option Pin & Register Compatible to HMC900LP5E Read/Write Serial Port Interface (SPI) 2 32 Lead 5x5 mm SMT Package 25 mm Functional Diagram 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.
