Quad PLL Clock Generator with Two-Wire Serial Interface

Features

  • Three output frequencies plus reference out
  • Programmable output frequencies through two-wire serial interface
  • Output frequencies from 4.9152 to 148.5 MHz
  • Uses an external 27 MHz crystal or 27 MHz input clock
  • Optional analog VCXO
  • Programmable output drive strength to minimize EMI
  • The equivalent without a serial port is the CY22388/89/91
  • 16-pin TSSOP package
  • 3.3 V operation with 2.5 V output buffer option

General Description

The CY24488 generates up to three independent clock frequencies, and a buffered copy of the reference crystal frequency, from a single crystal or reference input. Five clock output pins are available, which allows some frequencies to be driven on two or more output pins. Outputs can also be individually enabled or disabled. When a CLK output is individually disabled, it drives low.
