Parameter Description
Bit rate (Mbits/s) • 614.4
• 1228.8
• 2457.6
• 3072.0
• 4915.2
• 6144.0
• 9830.4
• 10137.6
614.4 Selects the CPRI line bit rate.
Arria V GZ devices support all line bit rates except
10.1376 Gbps. All other supported devices support
all CPRI line bit rates.
Operation mode • Master
• Slave
Master
Specifies whether the CPRI v6.0 IP core is
configured as a CPRI link master or a CPRI link
slave.
The value of this parameter determines the initial
and reset operation mode of the CPRI v6.0 IP core.
You can modify the IP core operation mode
dynamically by modifying the value of the
operation_mode
field of the
L1_CONFIG
register.
Supported receiver
CDR frequency
(MHz)
Per drop-down
menu
307.2
Specifies the incoming reference clock frequency
for the receiver CDR PLL, in MHz.
You must drive the input clock
xcvr_cdr_refclk
at the frequency you specify for this parameter.
