Altera transceiver for XAUI and GIGE modes

I want to reconfigure the tranaceiver for XAUI and GIGE modes.I have generated the altgx megafunction named xaui_gxb. I have set the Main PLL protocol to XAUI(refclk:156.25MHz and data rate 3125Mbps with 4 channels) and Alternate PLL configuration to Basic( refclk:125MHz and data rate 1250Mbps). Now when I compiled to generate the configuration MIF file, it gives the following error.

Error: The 'GXB PLL' 'CMU' parameter 'base_data_rate' is set to illegal value of '1250.0 Mbps' while the part is 'EP4SGX230FF35C3' and 'input_clock_frequency' is set to '125.0 MHz' on atom 'xaui_gxb:xaui_gxb|xaui_gxb_alt4gxb:xaui_gxb_alt4gxb_component|tx_pll_alt0'

If I set the Main PLL to SONET/SDH(OC-12) protocol it is compiling fine.

Can't figure out whether the problem is with Quartus or altgx configuration.
