IC1106: Silicon Tuner (Analog & DVB-T/C/T2)
Part number: Si2178-A20-GMR (SILICON LABS)
Sharp code: RH-IXD518WJZZY
Sharp code: RH-IXD518WJZZY
http://www.silabs.com/Support%20Documents/TechnicalDocs/Si2178-short.pdf
The Si2178 integrates a PAL/SECAM/NTSC analog TV demodulator with a universal hybrid TV tuner supporting all
worldwide digital and analog TV standards. The Si2178 requires no external balun and offers the lowest-cost BOM for
a hybrid TV tuner with analog demodulator. By combining Silicon Labs' proven digital low-IF architecture with a
4th-generation RF front-end, the Si2178 maintains the highest performance that exceeds MOPLL-based tuners,
including industry-leading 2nd-order distortion performance.
Compared with competing silicon TV tuners, the Si2178 delivers an unprecedented level of front-end integration,
resulting in the lowest number of external BOM components. No external tracking filters, wire-wound inductors, LNAs,
SAW filters or inductive power supply filtering components are needed. The Si2178 offers low power consumption as
well as an option for single or dual power supply operation. Also included is an internal power-on reset circuit,
eliminating the need for external brownout protection components or additional pins in module applications.
For next-generation digital TV broadcast standards, such as DVB-T2 and DVB-C2, that are sensitive to integrated phase
noise, the Si2178 offers industry-leading phase noise performance. A software-selectable cable mode is also included
which offers high return-loss performance.
As with prior-generation Silicon Labs TV tuners, the Si2178 delivers superior picture quality and a higher number of
received stations when compared to other silicon tuners and discrete MOPLL-based tuners. Both the tuner and analog
demodulator incorporate worldwide field testing experience from three previous generations in high-volume
production, to deliver the highest tolerance to real-world field reception conditions. The Si2178 also incorporates a
harmonic-rejection mixer that delivers excellent immunity to Wi-Fi and LTE interference across the full RF input
frequency range, with no need for external filtering components.
