RMS Output Interface and Transient Response
The HMC1010LP4 features digital input pins (SCI1-SCI4) that control the internal integration time constant. Output
transient response is determined by the digital integration controls, and output load conditions.
Shortest integration time is for SCI=0000, allowed longest integration time is for SCI=1100 (1101, 1110 and 1111 SCI
settings are forbidden states).
Using larger values of scI will narrow the operating bandwidth of the integrator, resulting in a longer averaging time-
interval and a more filtered output signal; however it will also slow the power detector’s transient response. A larger
scI value favors output accuracy over speed. For the fastest possible transient settling times set scI to 0000. this
configuration will operate the integrator at its widest possible bandwidth, resulting in short averaging time-interval
and an output signal with little filtering. Most applications will choose a SCI setting that maintains balance between
speed and accuracy. Furthermore, error performance over modulation bandwidth is dependent on the scI setting.
For example modulations with relatively low frequency components and high crest factors may require higher scI
(integration) settings.

Please contact Hittite customer support for single-ended tuning for other signal frequencies.
A DC bias (Vcc-1.2V) is present on the IN+ and IN- pins, and should not be overridden
