Applications
The Cypress CYW2330 is a dual serial input PLL frequency
synthesizer which includes a 2.5-GHz RF and a 600-MHz IF
dual modulus prescaler to combine the RF and IF mixer fre-
quency sections of wireless communication systems. The syn-
thesizer is designed for cordless/cellular telephone systems,
cable TV tuners, WLANs and other wireless communication
systems. The device operates from 2.7 V and dissipates only
24 mW.
