Interface AFE5801 and TMS320C6455
I'm working in portable ultrasound echography design.
Wich solutions are to interface 1 AFE5801 and 1 TMS320C6455 ?
Has TMS320C6455 external interface enough speed and capacity for 12x8 paralell data interface?
Case FPGA solution for data deserialization, some part recommendation?.
AFE5801 has two interfaces:
1. SPI interface is used to configure the registers of AFE5801. This can be done thru a controller or FPGA.
2. LVDS interface is used to send serialized ADC output to a deserializer. The deserializer is done using a XILINX FPGA - Vertex 4 (XC4VLX25).
I don't have any direct experience working with the 6455 external interface so can't comment on observed speeds/data rates, but here are some relevant links that might be helpful:
1. The EMIF user guide for C6455: http://focus.ti.com/lit/ug/spru971e/spru971e.pdf
2. There are some related posts here though of what others have observed with 6455's EMIF interface:http://e2e.ti.com/support/dsp/tms320c6000_high_performance_dsps/f/112/p/116968/417074.aspx#417074http://e2e.ti.com/support/dsp/tms320c6000_high_performance_dsps/f/112/p/61585/220803.aspx#220803
