altgxb_reconfig (megafuntion)

Altera_Forum · ‎06-20-2007

I have problems to re-configure the data rate of transceiver receiver with altgxb_reconfig megafuntion. What I wanted to do exactly is a data rate switch using clock dividers (change receptor from 2 to 1 Gbyte)s . In the page 2-225/6 of the document Stratix II GX device handbook, volume 2, can find the steps to continuing, but I get lost in the 6th. Did someone may detail to me by little more which are the steps to following?

Thanks

Hi,

I have done this on Stratix 4 Gx.

1) Instantiate ALTGX

2) Instantiate ALTGX_RECONFIG with data rate division option selected

3) Connect the two together

4) You dont need a mif file for this. Choose the correct mode for Stratix 4 its 011 and correct dividor (2'b01 in stratix 4) and just pulse write signal for one clock cycle

hallo,

and when do i need a .mif file?

What can i change by reconfiguring Channel and TXPLL select (CMUPLL, Channel reconfig with TXPLL selcet, ...)?

What does the CMUPLL do? Is it on the receiver side?

regards
