General Description

The CY22388 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.

Features

• 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

Benefits

• Meets most Digital Set Top Box, DVD Recorder, and DTV application requirements
• Multiple high-performance PLLs allow synthesis of unrelated frequencies
• Integration eliminates the need for external loop filter components
• Meets critical timing requirements in complex system designs
• Enables application compatibility
• Complete VCXO solution with ±120 ppm (typical pull range)
