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 I2S-bus interfaces.

Figure 1 shows the PNX8510/11 with a typical source decoder.
