1. Introduction
Welcome to the Cypress FX2LP – Legend Silicon based DMB-T/H TV Dongle Reference Design. This guide is a good
place to get started with the design. Included are the details of the design contents to get you on the way to developing your
TV Dongle design. The design has two versions, with LGS 8GL5 and LGS 8G75 demodulator from Legend Silcon.
1.1 Design Introduction
1.1.1 Block Diagram
The Cypress FX2LP and Legend Silicon based DMB-TH TV Dongle Reference Design consists of almost all files required
for the complete design. It has a tuner from ADI, which tunes the RF signal to the Legend Silicon demodulator. This sends
the TV signals in MPEG2_TS stream to Cypress FX2LP, which then sends them to the PC through the USB interface. In
the PC, the BDA driver forwards the data from the USB to the Media Player application where it is played.

2.4 Driver Installation
2.4.1 Firmware Loader Driver Installation
If TV Dongle does not have EEPROM to store the program, the hardware will be enumerated as a USB device. The
Cypress firmware loader driver then needs to be installed. Follow these instructions to install the driver.
Click on the No, not this time option and then click Next.
Select Install from a list or specific location (Advanced) and then click Next.
Browse to the folder \..\CY_FX2LP_LGS_ DMB-TH_TV Dongle\Driver\8G75 or \..\CY_FX2LP_LGS_ DMB-TH_TV
Dongle\Driver\8GL5 based on the demodulator used in the design; click Next.
