Applications

The Cypress CYW2338 is a dual serial input PLL frequency

synthesizer designed for high performance dual conversion

TV, VCR, and Set-top tuner sections, as well as downstream

receivers for cable modems. The CYW2338 is also well suited

for high-volume, low-cost wireless communications applica-

tions. One 2.5-GHz and 1.1-GHz prescaler, each with pulse

swallow capability are included. The device operates from

2.7V and dissipates only 27 mW.
