Description
Receiver controller clock input. For Cyclone IV GX devices only. The
frequency of this clock must be the same as rx_serial_refclk .
Because of hardware constraint, the transceiver PLL and core logic
cannot share the same clock input pin if they use transceiver PLL6
and PLL7.
This signal is related to the rx_video_format signal. Detects the
received video standard. Set input to 0 for a 148.35-MHz receiver
serial reference clock. Set input to 1 for 148.5-MHz RX serial
reference clock.
Transmitter clock out of transceiver. This clock is the output of the
voltage-controlled oscillator (VCO) and is used as a parallel clock for
the transmitter. It connects internally to the tx_clkout signal of the
ALTGX or ALT2GXB megafunction.
Transceiver CDR clock.
67.5-MHz oversample clock output for cascading MegaCore
functions. SD-SDI only.
This signal is related to the refclk_rate signal. Indicates the
format for the received video. The rx_video_format value is valid
after the frame locked signal is asserted.
For more information about the video specification, refer to
Notes to Table 3–12 :
(1) You must tie the tx_serial_refclk and rx_serial_refclk signals together if you generate an SDI duplex using the Stratix V or Arria V
devices.
(2) For Cyclone IV GX devices, set the refclk_rate according to the rx_coreclk frequency.
Table 3–13 lists the transmitter clock signals.

Description
Transmitter parallel clock input. For SD-SDI = 27 MHz;
for HD-SDI = 74 MHz and for 3G-SDI = 148.5 MHz.
Transceiver reference clock input. Low jitter. Refer to Table 3–5 .
Optional port for transceiver reference clock input. Low jitter. Similar
to tx_serial_refclk . Only available for Arria II, Stratix IV GX, and
HardCopy IV GX devices.
Note to Table 3–13 :
(1) You must tie the tx_serial_refclk and rx_serial_refclk signals together if you generate an SDI duplex using Arria V or Stratix V
devices.
