USB Low-Full-High Speed Peripherals

New Contributor II

Hi there 😉

I have a DVB-s2 Tuner that needs to be connected to a Linux machine using the CY7C68013a  FX2LP.

Interface from the demodulator is 8-Bit parallel TS transport stream.

There is also a serial TS interface but i guess thats too fast to capture.

On the Linux i guess its necessary to use libusb and write an application to read the data and control the channels.

The reference designs "CY_FX2LP_LGS_ DMB-TH_TV Dongle", there is a folder "firmware->USBTV".

is that for the CY7C68013a  - chip? to be downloaded on connect?

What SDK do i need to compile this firmware?

I have just an CY7C68013a  mini board.

Thanks!

Hello,

You can use the design files present in this link: https://community.cypress.com/t5/USB-Low-Full-High-Speed/FX2LP-DMB-T-H-TV-Dongle-Reference-Design-on...  

It has the firmware and hardware files. 

You can install and use the FX2LP DVK package for the development purposes: https://www.cypress.com/documentation/development-kitsboards/cy3684-ez-usb-fx2lp-development-kit  

It installs Keil uVision 2 and GPIF Designer for firmware development and the  drivers as well.

 

Thanks,

Thank you;)

It looks like i have to go all the way and understand the windows driver as well.

Is there any sourcode for the Windows 8G75 driver?

Also.. there are actually 2 examples for DVB TS capture:

- FX2LP_DMB_TH_TV_Dongle

- 001-58069_AN58069_Implementing_an_8_Bit_Parallel_MPEG2_TS_Interface_Using_Slave_FIFO_Mode_in_FX2LP

Does anyone know if there is a fundamental difference regarding the cypress chip?

Hello,

The application note AN58069 explains how to implement an 8-bit parallel MPEG2-TS interface using the Slave FIFO mode.

FX2LP DMB-T/H TV Dongle is a reference 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.

We give out only the driver files in the design.

Thanks,

Yatheesh
