The M88TS2022 is a single-chip, direct-conversion tuner for digital satellite receiver applications. It offers the industry's most integrated solution and simplifies the front-end designs. The device also provides an RF bypass output for driving a second tuner module.
This device incorporates the following functional blocks on a single chip: an LNA, quadrature down-converting mixers, a low phase noise and fast locking frequency synthesizer with on-chip loop filters, a DC offset cancellation loop with integrated loop filters, self-calibrated programmable baseband channel filters, an integrated RF AGC loop, and crystal oscillators with an integrated auxiliary clock output. As a result, the M88TS2022 has the least number of pins compared with other conventional solutions, and requires the least external components. The device also has the industry’s smallest latency, as it uses a fast locking PLL and a fast settling DC offset cancellation architecture.
The M88TS2022 is configured via a 2-wire serial interface.
