Short CCT Protection Circuit

Short circuit protection is necessary for protecting chassis and main IC against damages 
when  any  Vcc  supply  shorts  to  ground.  Protect  pin  should  be  logic  high  while  normal 
operation.  When  there  is  a  short  circuit  protect  pin  shold  be  logic  low.  After  any  short 
detection, SW forces LEDs on LED card to blink.

The  MSD9WB7PX-2  integrates  DTV/multi-media  all-purpose  AV  decoder,  DVB-T 
demodulator,  VIF  demodulator, and  Sound/Video  processor  into  a  single  device.  This 
allows  the  overall  BOM  to  be  reduced  significantly  making the  MSD9WB7PX-2  a  very 

competitive multi-media DTV solution. For ATV users, the MSD9WB7PX-2 provides multi-
standard  analog  TV  support  with  adaptive  3D  video  decoding  and  VBI  data  extraction. 
The build-in audio decoder is capable of decoding FM, AM, NICAM, A2, BTSC and EIA-J 
sound standards. The MSD9WB7PX-2 supplies all the necessary A/V inputs and outputs 
to complete a receiver design including a multi-port HDMI receiver and component video 
ADC.  All  input  selection  multiplexed  for  video  and  audio  are  integrated,  including full 
SCART  support  with  CVBS  output.  The  equipped  MStar  MACE-5  color  engine  is  the 
latest masterpiece from MStar famous color engine series providing excellent video and 
picture  quality  in  Full-HD  and  large-scale displaying  system. To  meet  the  increasingly 
popular  energy  legislative  requirements  without  the  use  of  additional  hardware,  the
MSD9WB7PX-2 has an ultra low power standby mode during which an embedded MCU 
can act upon standby events and wake up the system as required.

MSD9WB9PX-2, an SOC solution that supports channel decoding, MPEG decoding, and 
media-centre  functionality  enabled  by  a  high  performance  AV  CODEC  and  CPU  Key
