2 Baseband Board


The baseband board functionality of a Wireless Base Station Transceiver includes: 1) Separating received signals into channels by combining correct time slots or coded messages. 2) Sending these signals to the Base Station Controller for compression. 3) Changing to another channel when directed by the BSC. 4) Converting channels back into analog, combining multiple voice channels, up-converting to IF, filtering, and amplifying signals for transmission to mobile subscribers.

Component Highlights

*Buck switching regulators - provide high-efficiency, high- power density power conversion.

*Ethernet PHY - small size, low power, fully interoperable Ethernet PHY delivers up to 1 Gbps performance.

*Select from several hardware monitors, RDTS 2-wire serial temperature sensors and SPI/Microwire compatible digital sensors.

*LVDS - SerDes and PHY products for reliable high speed data and clock distribution.
