Honored Contributorgxb2_cal_clk in SDI-receiver
Hello
I use SD-SDI receiver in ArriaGX device. Global clock in project - 27MHz. rx_sd_oversample_clk_in - 67.5 MHz what calibration clock I must to connect to 'megafunction input "gxb2_cal_clk"? The same question for HD-SDI receiver. rx_seral_refclk - 74.25 MHz thank you3 Replies
Altera_Forumin devices like Stratix IV GX, you need a calibration and reconfiguration clock. the overlap of the two ranges makes 50 MHz a common choice
- Altera_Forum
any value of frequencies from 10 to 125 MHz?
Are there any recomendetions, how to choose the value - Altera_Forumpage 7: cal_blk_clk Input Calibration clock for the transceiver termination blocks. This clock supports frequencies from 10 MHz to 125 MHz.
