1.1. U400 (MT5337PKR PBGA-465)
Notes: The function of MT5337PKR is same as the function of MT5336PKR except the below 2 items:
1). The MT5337PKR support de-blocking filter, but MT5336PKR has not this function.
2). The MT5337PKR supports up to 1920x1080 panel and VGA dot-to-dot. The MT5336PKR supports up to 1680x1050 panel and
VGA dot-to-dot.
GENERAL DESCRIPTION
The MediaTek MT5337PKR family consists of a backend decoder and a TV controller and offers high integration for advanced applications. It combines a
transport de-multiplexer, a high definition MPEG-2 video decoder, an MPEG2 audio decoder, an LVDS transmitter, and an NTSC/PAL/SECAM TV
decoder with a 3D comb filter. The MT5337PKR enables consumer electronics manufactures to build high quality, low cost and feature-rich iDTVs.
World-Leading Audio/Video Technology : The MT5337PKR family has built-in high resolution and high-quality audio codec. It includes MediaTek
MDDi
TM
de-interlace solution to generate very smooth picture quality for motions. A 3D comb filter added to the TV decoder recovers great detail for still
pictures. The special color processing technology provides natural, deep colors and true studio quality graphics.
Rich Features for High Value Products : The MT5337PKR family enables a true single-chip experience. It integrates high-quality HDMI1.3, high speed
VGA ADC, dual-channel LVDS, and USB2.0 receiver.
Reliable Front-end Receiving Capability : Excellent adjacent and co-channel rejection capability grants customers never miss any wonderful stream.
Professional error-concealment provides stable, smooth and mosaic-free video quality.
