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?
