Philips Nexperia PNX2000 Operation manual

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.

Interface Description
I2C-bus The PNX2000 IC is controlled using an I2C-bus. It performs like an I2C-bus to PI-bus
bridge, i.e. translates I2C-bus slave received commands to PI-bus master commands.
I2D Receives data in three streams from PNX3000.
I2S-bus Serial digital audio interface (6 stereo inputs, 6 stereo outputs) for connection to other
devices that support the I2S-bus standard. Can be used to receive decoded sound
from a multi-channel digital audio decoder, provide additional ADCs and DACs, or loop
audio signals through an external processor or delay line.
ITU-656 Mainly intended to transfer output data stream externally to the PNX8550, but the
output data stream could also be readable by other ITU-656 input devices that
implement data valid signalling.
DACS Digital-analog converters used to generate analog outputs from Sound Core.

8. Television application
Figure 3 shows an overview of the top level hardware architecture of a TV application,
using the PNX3000 and PNX2000 as an analog front-end and the PNX8550 as the main
processor. This system is aimed at the hybrid (analog or digital) TV market.
The main SOC in the system, PNX8550, performs key features for high quality television
like video quality enhancement, motion compensation and picture-in-picture processing.
PNX2000 together with PNX3000 are used to perform the input decoding of a single
stream of analog audio and a single stream of analog video (1fHor 2fH) broadcast signals.
PNX2000 performs the following main functions:
•Color decoding into ITU-601 compatible format (1fHor 2fH).
•A digital interface to external 3D comb filter.
•VBI data capture (Teletext, WSS, CC).
•ITU-656 formatting for communication to PNX8550.
•Audio demodulation and decoding.
•Audio processing and D-A conversion.
The audio data is transferred between PNX2000 and PNX8550 using I2S-bus. PNX2000
and PNX3000 are controlled from PNX8550 via the I2C-bus.
