CY22M1LCALGXI-00

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22M1LCALGXI-00 is a single-output, low-power programmable clock generator designed for portable applications. It operates at 1.8 V and generates output frequencies from 1 to 80 MHz using a PLL-based architecture. The device accepts an 8–48 MHz fundamental tuned crystal or a 1–80 MHz external reference clock. Key features include a small 8-pin QFN package (1.7 mm x 1.7 mm), programmable drive strength, and configurable power management modes. It supports asynchronous or synchronous OE/PD# control and includes an internal capacitor tuning array for frequency fine-tuning.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'I' confirms industrial temperature rating (-40°C to +85°C) and 'L' indicates 1.8 V operation. Confirm whether the specific part number requires factory programming or field programmability via the CyClockMaker kit. Ensure the application circuit matches the recommended crystal specifications for the selected input frequency range.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single LVCMOS clock output is required in space-constrained designs. Choose the CY22M1L variant specifically for 1.8 V systems. Verify that the required output frequency falls within the 1–80 MHz range and that the input source is compatible with either a fundamental crystal (8–48 MHz) or an external clock signal (1–80 MHz).
