CY24488: Quad PLL Clock Generator with Two-Wire Serial Interface | Cypress Semiconductor
CY24488: Quad PLL Clock Generator with Two-Wire Serial Interface
Quad PLL Clock Generator with Two-Wire Serial Interface
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
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.
Dear valued customer,
Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
