Description

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.
