CY22392FXA

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22392FXA is an Automotive A-Grade, three-PLL, general-purpose flash programmable clock generator manufactured by Infineon Technologies. It operates on a single 3.3 V supply and features six CMOS outputs capable of generating frequencies up to 166 MHz from an external reference source ranging from 8 MHz to 30 MHz for crystals or 1 MHz to 166 MHz for driven clocks. The device utilizes ultra-wide divide counters (8-bit Q, 11-bit P, and 7-bit post-divide) to enable precise frequency generation with 0 ppm accuracy. Key electrical parameters include a typical power supply current of 100 mA under heavy load, a peak-to-peak period jitter of 400 ps, and a duty cycle of 50% (ranging from 40% to 60% at higher frequencies). It is housed in a 16-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix ZZ16 corresponds to the tube packaging format required for your assembly line. Confirm that the 'F' designation indicates a field-programmable unit requiring in-house programming via CyberClocks software before installation. Ensure the automotive A-grade temperature range (-40 °C to +85 °C) aligns with your system's environmental specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems requiring multiple distinct clock frequencies derived from a single reference source. The CY22392FXA is suitable for designs needing glitch-free frequency switching via S0-S2 inputs. Consider the 16-pin TSSOP footprint for board space constraints. Verify that the 166 MHz maximum output frequency meets the requirements of the target digital components.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY22392FXA belongs to the CY22392 family, which serves as a functional upgrade to the legacy CY2292 series. It incorporates improved linear crystal load capacitors and wider frequency ranges compared to its predecessors. The device is part of Infineon's automotive-grade portfolio, ensuring compliance with reliability standards for vehicle electronics.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The CY22392ZXA series represents factory-programmed variants within the same family. These units offer identical electrical characteristics but are pre-configured for high-volume production, eliminating the need for field programming.
