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.
