Clock Dividers Designed for RF Transmitter, Basestation Apps

( 1 Mar 2008 )

Micrel Inc. has added four new divide-by-three and divide-by-five clock dividers to its clock divider product family. The SY89228/229 are 1GHz LVPEC L/LVDS dividers that feature Fail Safe Input (FSI) circuitry and the SY89230/231 are 3.2GHz LVPECL/LVDS dividers.

Targeted applications include pre-scaling functions, PLL clock generation and distribution, RF transmitters, and wireless base stations. The SY89228U and SY89229U are optimized to prevent unwanted oscillations and maintain output stability when an input signal's swing collapses or disappears.
