Supplier Device Package 48-SSOP

The CY28349BOCT is a clock synthesizer and driver from Cypress Semiconductor, designed for low-frequency timing applications. With a PLL-based architecture, it accepts LVTTL or Crystal inputs and delivers clock outputs at up to 1MHz. Housed in a 48-BSSOP package, it operates from 0°C to 70°C, making it suitable for industrial and consumer electronics.

  • PLL-Based Synthesis: Ensures accurate frequency generation from a low-frequency reference.
  • Multiple Input Options: Accepts LVTTL or Crystal for design flexibility.
  • Wide Package: 48-BSSOP allows for easy PCB integration.
  • Reliable Operation: Designed for 0°C to 70°C environments.

Low-Frequency System Clock Generation

Generate precise 1MHz clocks for legacy microcontrollers and real-time clocks in embedded systems.

Industrial Control Timing
