SAA7134HL中文资料飞利浦数据手册PDF规格书

GENERAL DESCRIPTION

The SAA7134HL is a single chip solution to digitize and decode video and sound, and to capture both data streams through the PCI-bus.

FEATURES

PCI and DMA bus mastering

• PCI 2.2 compliant including full Advanced Configuration and Power Interface (ACPI)

• System vendor ID, etc. via EEPROM

• Hardware support for virtual addressing by MMU

• DMA bus master write for video, audio, VBI and TS

• Configurable PCI FIFOs, graceful overflow

• Packed and planar video formats, overlay clipping.

TV video decoder and video scaling

• All-standards TV decoder: NTSC, PAL and SECAM

• Five analog video inputs: CVBS and S-video

• Video digitizing by two 9-bit ADCs at 27 MHz

• Sampling according ITU-R BT.601 with 720 pixels/line

• Adaptive comb filter for NTSC and PAL, also operating for non-standard signals

• Automatic TV standard detection

• Three level Macrovision copy protection detection according to Macrovision Detect specification Revision 1

• Control of brightness, contrast, saturation and hue

• Versatile filter bandwidth selection

• Horizontal and vertical downscaling or zoom

• Adaptive anti-alias filtering

• Capture of raw VBI samples

• Two alternating settings for active video scaling

• Output in YUV and RGB

• Gamma compensation, black stretching.

TV sound decoder and audio I/O

• TV stereo decoding for NICAM and dual FM

• Audio sampling locked to video field rate, no drift of audio stream against video stream

• On-chip stereo audio ADCs and DACs (2 × 16-bit)

• Sampling rate, e.g. 32, 44.1 and 48 kHz

• Integrated analog audio pass-through for analog audio loop back cable to sound card.

Peripheral interface

• I2C-bus master interface: 3.3 and 5 V

• Digital video output: ITU and VIP formats

• TS input: serial or parallel

• General purpose I/O, e.g. for strapping and interrupt

• Propagate reset and ACPI state D3-hot.

General

• Package: LQFP128

• Power supply: 3.3 V only

• Power consumption of typical application: 1 W

• Power-down state (D3-hot): <20 mW
