Description



Features:

· Multi-standard vision IF circuit with alignment-free PLL demodulator without external components
· Internal (switchable) time-constant for the IF AGC circuit
· DTV IF circuit for gain control of digital broadcast TV signals
· Sound IF amplifier with separate AGC circuit for quasi-split sound
· IF circuit can also be used for intercarrier sound
· Analog demodulator for AM sound
· Integrated sound trap and group delay correction
· Video ident function detects the presence of a video signal
· Video source selector with four external CVBS or YC inputs and two analog CVBS outputs with independent source selection for each output
· Two linear inputs for 1fH or 2fH RGB signals with source selector; the RGB signals are converted to YUV before A to D conversion; both inputs can also be used as YPbPr input for DVD or set top box
· Integrated anti-alias filters for video Analog to Digital Converters (ADCs)
· Four 10-bit video ADCs for the conversion of CVBS, YC,YUV and down-mixed sound IF signals
· Up to three different A to D converted video channels are available simultaneously (e.g. CVBS, YC and YUV)
· Audio source selector with five stereo inputs for analog audio and two microphone inputs
· Two microphone amplifiers with adjustable gain
· Three analog audio outputs for SCART and line out with independent source selection for each output
· Four 1-bit audio sigma delta ADCs for the conversion of audio and microphone signals
· Three serial data link transmitters for interfacing with the digital video processor at a bit rate of 594 Mbit/s per data link
· Voltage to current converter for driving external east-west power amplifier
· I2C-bus transceiver with selectable slave address and maskable interrupt output.

Description

The PNX3000 is an analog front end for digital video processors. It contains an IF circuit for both analog and digital broadcast signals, input selectors and ADCs for analog video and audio signals. The digital output signals are made available via three serial data links.

The IC has a supply voltage of 5 V. The supply voltage of the analog audio part can be 5 V or 8 V, depending on the maximum signal amplitudes that are required.
