Si2157

Worldwide Digital and Analog TV Tuner

Description

A universal hybrid TV tuner, the Si2157 supports

digital and analog reception for all worldwide

terrestrial and cable TV standards. By combining

Silicon

Laboratories’

proven

digital

low-IF

Si2157 maintains the highest performance that

exceeds that of MOPLL-based tuners, including

Pin- and API-compatibility to the previous generation

minimize customers’ development effort.

The Si2157 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

order

distortion

compromising

reception.

Silicon

Laboratories’

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 Si2157 rises to

the challenge, delivering industry-leading integrated

phase noise. Additionally, a software-selectable

cable mode offers optimized return loss.

The Si2157 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 Si2157 delivers the highest tolerance

to real-world reception conditions.
