CY24488
CY24488 is Quad-PLL Clock Generator manufactured by Cypress.
Quad-PLL Clock Generator with Two-Wire Serial Interface
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
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 ponents
- plete VCXO solution with ± 120 ppm (typical pull range)
Functional Description
The CY24488 generates up to three independent clock frequencies, and a buffered copy of the...
