Revised December 11, 2003
Features
Integrated phase-locked loop (PLL)
Low-jitter, high-accuracy outputs
VCXO with analog adjust
3.3V operation
Compatible with MK3727 (–1, –4, –5, –6, –7)
Benefits
Highest-performance PLL tailored for multimedia applica-
tions
Meets critical timing requirements in complex system
designs
Large ±150-ppm range, better linearity
Application compatibility for a wide variety of designs
Enables design compatibility
Advanced Features
Serial programming interface (CY2410-3 only)
Lower drive strength settings (CY2410-4, -6)
Matches nonlinear MK3727A VCXO control curve (-5, -6)
Matches nonlinear MK3727C VCXO control curve (-7)
Benefits
Digital VCXO control
Electromagnetic interference (EMI) reduction for standards
compliance
Second source for existing designs
