The 5th generation universal hybrid TV tuner, the Si2181 supports digital and analog reception for all worldwide terrestrial and cable TV standards. By combining our proven digital low-IF architecture with a 5th-generation RF front-end, the Si2181 maintains the highest performance that exceeds that of MOPLL-based tuners, including industry-leading 2nd order distortion performance. Pin and API compatibility to the previous generation minimize customers’ development effort. The Si2181 delivers unprecedented integration with no external balun, tracking filters, LNAs, SAW filters or inductive power supply filtering.
While other solutions may also eliminate the balun, they suffer degradation in NF and 2nd order distortion compromising reception. Our proprietary and field-proven architecture delivers not only an optimized BOM but also world-class system performance. Options for single or dual supply and internal power-on reset are included. A harmonic rejection mixer delivers outstanding immunity to Wi-Fi and LTE interference, replacing the need for external filtering.
For advanced digital terrestrial TV reception, DVB-T2 and DVB-C2 constellations demand outstanding phase noise specifications, and the Si2181 family rises to the challenge, delivering industry-leading integrated phase noise. Additionally, a software-selectable cable mode offers optimized return loss. The device delivers exceptional picture quality and a higher number of received stations when compared to other solutions. Incorporating worldwide field experience from four prior tuner generations in mass production, the Si2181 delivers the highest tolerance to real-world reception conditions.
