Spezifikationen
CY22150KFZXC is an Infineon (ex-Cypress) single-PLL flash-programmable multi-output clock generator, a commercial-grade frequency synthesizer with six independent CMOS clock outputs, designed to replace multiple fixed crystal oscillators in embedded mainboards, communication equipment and industrial control hardware for flexible multi-frequency clock distribution.
👉 It is not fixed-frequency single-output crystal oscillator or spread-spectrum EMI reduction clock chip.
👉 It is a field-reprogrammable general-purpose clock source supporting custom frequency configuration via I2C or offline flash programming, ideal for cost-sensitive multi-clock embedded systems to simplify BOM and PCB layout.
Core Key Features
- Integrated Single PLL Frequency Synthesis
- Accept dual input modes: external 8–30 MHz crystal, or external driven clock 1–133 MHz
- Output frequency range: 80 kHz ~ 166.6 MHz (3.3V supply, commercial grade)
- Flexible frequency calculation formula: CLK = ((REF × P)/Q) / post-divider; each of the 6 outputs supports independent divider setting
- Low phase jitter & low output skew between channels, stable timing for MCU, FPGA, Ethernet and memory peripherals
- Six Independent Configurable Clock Outputs
- All outputs CMOS level, support optional 2.5V low-voltage swing under 3.3V core power supply
- Each output configurable for enable/disable, frequency division, 50% fixed duty cycle
- Channel skew minimized for synchronous multi-peripheral clock supply
- Flash Non-Volatile Reprogrammable Architecture
- On-chip flash memory stores custom frequency parameters; supports up to 100 times re-programming
- Two programming modes:
- Offline factory programming via dedicated CY3672 development kit before SMT assembly
- In-system I2C two-wire serial field programming, modify frequencies on board without rework
- Eliminates stocking dozens of fixed crystal variants, unifies BOM across multiple product models
- Electrical & Packaging Specs
- Operating supply voltage: 3.135V ~ 3.465V (nominal 3.3V)
- Commercial temperature grade: 0°C ~ +70°C junction temperature
- 16-pin narrow-body TSSOP package (4.4mm width), compact footprint for dense PCB layout
- Tape-and-reel packaging, Ni/Pd/Au lead finish, fully RoHS lead-free compliant for mass SMT production
- System Compatibility
- Standard I2C two-wire serial bus for runtime register configuration
- No external loop filter components required; integrated PLL passive components to reduce peripheral count
- Low static power consumption, suitable for continuous 24-hour equipment operation
