Philips Nexperia PNX2000 Manuale operativo

1. General description

The PNX2000 is a companion IC for use with the Nexperia™ 1digital video home

entertainment engines such as PNX8526 and PNX8550.

The PNX2000 is always used in combination with the PNX3000.

PNX2000 is intended for mid to high-end analog and hybrid TV sets, performing input

decoding of single stream analog audio and single stream analog video signals. In

addition, the PNX2000 is used for decoding and presentation of all audio output streams

in the system. Figure 1 shows a block diagram of the device.

2. Features

■Detection of PAL, NTSC or SECAM, and various 1fHand 2fHcomponent video input

sources.

■Full support for 1fHand 2fHvideo sources; progressive and interlaced.

■Decoding for global VBI Standards (WST, WSS, VPS, CC, VITC).

■ITU-656 output interface.

■Global multi-standard audio demodulation and decoding.

■Dolby Pro Logic II™ 2multi-channel audio decoding and post-processing.

■Advanced fully programmable audio post-processing functions, including

psychoacoustic spatial algorithms for optimal loudspeaker matching.

3. Applications

■Analog TV receivers.

■Hybrid TV receivers.

■DVD recorders.

■VCRs.
