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 bine the RF and IF mixer frequency sections of wireless munication systems. The synthesizer is designed for cordless/cellular telephone systems, cable TV tuners, WLANs and other wireless munication systems. The device operates from 2.7 V and dissipates only 24 m W.
