Clock Networks and PLLs in Intel Cyclone 10 LP Devices 683777 | 2023.02.15 The post-scale counters have two control bits: • rbypass—For bypassing the counter • rselodd—For selecting the output clock duty cycle When the rbypass bit is set to 1, it bypasses the counter, resulting ...

Lock Detect Each PD (Phase Detector) cycle, the HMC703LP4E measures phase error at the PD. The measured phase error must be: • < ~220 degrees if 40 MHz <= fPD <= 120 MHz, and • < ~14 ns if fpd < 40 MHz, for a number of consecutive cycles (number of cycles is ...
Mode 1 of Timer 1 supports 16-bit auto-reload to facilitate longer time-out periods for generating low baud rates. 7.6 Watchdog Timer The Watchdog Timer in AT89LP2052/LP4052 counts at a rate of once per clock cycle. This compares to once every 12 clocks in the standard 8051. 7 3547...

The LP5523 has a built-in temperature-sensing element, and PWM duty cycle of the LED drivers changes linearly in relationship to changes in temperature. User can select the slope of the graph (31 slopes) based on the LED characteristics (see Figure 13). This compensation can be done either...
