MAXQ3183 Maxim, MAXQ3183 Datasheet - Page 78

• Manufacturer Part Number: MAXQ3183
• Description: The MAXQ3183 is a dedicated electricity measurement front-end that collects and calculates polyphase voltage, current, power, energy, and many other metering and power-quality parameters of a polyphase load
• Manufacturer: Maxim

Low-Power, Multifunction, Polyphase AFE
with Harmonics and Tamper Detect
This register contains the system clock frequency in kHz units. Because the default frequency is 8MHz, this register
defaults to 0x1F40.
This register contains the number of line cycles that will be accumulated in a single DSP cycle. When CYCNT line
cycles have been accumulated, the DSP performs power, power factor, and energy calculations. By default, the
cycle count is 0x10 (16 decimal).
