SKY13292-365LF Block Diagram JEDEC J-STD-020) Skyworks offers lead (Pb)-free, RoHS (Restriction of Description Hazardous Substances) compliant packaging. The SKY13292-365LF is a four-input to two-output switch matrix intended for Direct Broadcast Satellite (DBS) switching and cable TV/modem applications. The SKY13292-365LF enables 16 states, directing any of the four inputs to either of the two outputs. Switch states are selected using tone and voltage signals together with logic levels applied to mode control inputs. The switch can operate over a temperature range of 40 C to +85 C. The SKY13292-365LF is manufactured in a compact, 4 x 4 mm, 20-pin Quad Flat No-Lead (QFN) package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Skyworks Solutions, Inc.
