SI2151集成電路（IC）的視頻處理規(guī)格書(shū)PDF中文資料

SI2151屬于集成電路（IC）的視頻處理。由美國(guó)思佳訊公司制造生產(chǎn)的SI2151視頻處理一種集成電路 (IC) 半導(dǎo)體器件，設(shè)計(jì)用于在放大、增強(qiáng)、編碼器和解碼器（編解碼器）、緩沖、校準(zhǔn)、處理、信號(hào)調(diào)節(jié)、調(diào)制與解調(diào)、轉(zhuǎn)換、傳輸、伽瑪校正、切換、OSD、數(shù)字化和多路復(fù)用等應(yīng)用中處理音頻和/或視頻信號(hào)。

Description

The Si2151 is the industry's most advanced hybrid TV

tuner supporting all worldwide terrestrial and cable TV

standards for digital and analog TV reception. Leveraging

five generations of field-proven hybrid TV tuner technology,

the Si2151 delivers the same or better RF performance as

Skyworks' Si2157 hybrid TV tuner while further reducing

footprint size and bill of materials cost.

Available in an industry-leading 3x3 mm QFN package, the

Si2151 eliminates the need for an external balun, LNAs,

SAW filters, and inductive power supply filtering to deliver

the lowest-cost, most design-friendly and area-efficient

solution available today. While competing solutions may

also eliminate the balun, they suffer degradation in NF and

second-order distortion, compromising reception. A fullyintegrated

1.8 V LDO enables single supply operation,

while a dual supply option offers additional system

flexibility. Increased immunity to LTE interference and a

harmonic rejection mixer with outstanding immunity to Wi-

Fi interference eliminate the need for external filtering.

For advanced digital broadcast standards with high-order

constellations, such as DVB-T2 and DVB-C2, the superior

integrated phase noise of the Si2151 provides several dB

of improved reception performance compared to

competing solutions. Additionally, a software-selectable

cable mode offers optimized return loss.

The Si2151 delivers exceptional picture quality and a

higher number of received stations when compared to

other silicon tuners. Incorporating worldwide field

experience from five prior hybrid tuner generations in mass

production, the Si2151 delivers the highest tolerance to

real-world reception conditions.
