PNX8511 Overview

Analog companion chip

PNX8510; PNX8511
Analog companion chip
Rev. 04 – 12 January 2004
Product data
1. General description
The PNX8510; PNX8511 is an analog backend companion chip to digital ICs
processing video and audio signals.
The primary difference between the PNX8510 and the PNX8511 is:
PNX8510 includes the
Macrovision™
pay-per-view copy protection system
PNX8511 does not include
Macrovision™
PNX8510/11 provides two video encoders through two standardized D1 interfaces.
The encoders can be bypassed to get direct access to the video DACs for higher
resolution displays. PNX8510/11 also contains a sophisticated sync raster engine
which can be utilized to generate various synchronization patterns for interlaced and
non-interlaced image formats. The sync raster engine together with an up-sampling
filter and a sync insertion unit compose a complete HDTV-capable data path
including tri-level sync generation.
PNX8510/11
also provides two independent pairs of stereo audio DACs with two
corresponding I

S-bus interfaces.
