Highly integrated tuner IC

Maxim Integrated Products has introduced the MAX2163A, a silicon tuner for use in 1- and 3-segment, ISDB-T applications operating in the VHF and UHF frequency bands. Fabricated using Maxim's SiGe BiCMOS process, this device offers the performance benefits of SiGe with the power consumption of CMOS. The performance benefits include 99dB dynamic range and good adjacent-channel performance. The MAX2163A is suitable for cell phones, portable media players (PMPs), and automotive infotainment systems. The IC contains all of the circuit blocks needed to receive ISDB-T, except a crystal and cellular rejection filter. Internal RF blocks include variable bandwidth lowpass filters, optional VHF and UHF tracking filters, and on-chip power detectors that enable closed-loop automatic gain control (AGC) of the device. Control is achieved through a 2- or 4-wire digital interface, and the IC can be shut down through either the digital bus or a hardware pin. The IC is available in either a 6mm x 6mm, 40-pin TQFN package or a custom, 40-bump wafer-level package (WLP). Both versions are specified over the -40°C to +85°C temperature range.
