Cypress CY22388FZXC

Генератор тактовых импульсов PLL

Overview

The CY22388FZXC family of devices has an Analog VCXO (Voltage Controlled Crystal Oscillator), 4 PLLs, up to 8 clock outputs and frequency selection capabilities. The frequency selects do not modify any PLL frequency. Instead they allow the user to choose between up to 8 different output divider selections depending on the clock and package configuration. This is illustrated in the following Frequency Selection tables and Functional Block Diagram.

• Fully integrated phase-locked loops (PLLs)• QFN package:• 40% smaller than 20-pin TSSOP• 22% smaller than 16-pin TSSOP• Selectable Output Frequency• Programmable Output Frequencies• Output Frequency Range of 5–1 66 MHz• Input Frequency Range• Crystal: 1 0–30 MHz• External Reference: 1 –1 00 MHz• Analog VCXO• 16-/20-pin TSSOP and 32-pin QFN packages• 3.3V operation with 2.5V output buffer option
