The Si2178/58/48/38/28 is Silicon Labs' fourth-generation hybrid TV tuner family supporting all worldwide terrestrial and cable TV standards. Requiring no external balun, SAW filters, wirewound inductors or LNAs, the Si21x8 offers the lowest-cost BOM for analog, digital and hybrid TV tuners, with or without a demodulator. Also included are an integrated power-on reset circuit and an option for single power supply operation.
As with prior generation Silicon Labs TV tuners, the Si21x8 maintains very high linearity and low noise to deliver superior picture quality and a higher number of received stations than other silicon tuners and discrete MOPLL-based tuners.
