Table 67.  Transceiver Clocks Specifications for Intel® Stratix® 10 H-Tile Devices
Clock Value Unit
reconfig_clk ≤ 150 MHz
fixed_clk for the RX detect circuit 250 ± 20% MHz

For OSC_CLK_1 specifications, refer to the External Configuration Clock Source Requirements section.

97 The 25 MHz is only available when HDMI is selected for fPLL protocol mode.
98 To calculate the REFCLK phase noise requirement at frequencies other than 800 MHz, use the following formula: REFCLK phase noise at f (MHz) = REFCLK phase noise at 800 MHz + 20*log(f/800).
99 A phase noise (PN) mask overrides the REFCLK noise.
100 The maximum data rate depends on speed grade.
101 If the upper ATX PLL in a bank is used as the main GXT PLL, then the channel span includes two GXT channels from the bank above. If the lower ATX PLL in a bank is used as the main GXT PLL, then the channel span includes two GXT channels from the bank below.
102 The device cannot tolerate prolonged operation at this absolute maximum.
103 A passive pull up resistance prevents a 0-V common mode voltage on AC coupled receiver pins before the FPGA is configured.
104 Bonded channels operating at data rates above 16 Gbps require 1.12 V ± 20 mV at the pin. For channels that are placed in the same H-Tile as the channels that required 1.12 V ± 20 mV, VCCR_GXB = 1.12 V ± 20 mV.
105 For GXT channels, VCCR_GXB must be 1.12 V. For GX channels, VCCR_GXB must be 1.03 V. VCCR_GXB must be 1.12 V for the transceiver on the same H-Tile when using GX and GXT channels together.
106 tLTR is the time required for the receive CDR to lock to the input reference clock frequency after coming out of reset or after CDR calibration is completed.
107 tLTD is time required for the receiver CDR to start recovering valid data after the rx_is_lockedtodata signal goes high.
108 tLTD_manual is the time required for the receiver CDR to start recovering valid data after the rx_is_lockedtodata signal goes high when the CDR is functioning in the manual mode.
109 tLTR_LTD_manual is the time the receiver CDR must be kept in lock to reference (LTR) mode after the rx_is_lockedtoref signal goes high when the CDR is functioning in the manual mode.
110 High Speed Differential I/O is the dedicated I/O standard for the transmitter in Intel® Stratix® 10 transceivers.
111 For GXT channels, VCCT_GXB must be 1.12 V. For GX channels, VCCT_GXB must be 1.03 V. VCCT_GXB must be 1.12 V when using GX and GXT channels together within the same H-Tile.
112 DC coupling specifications are pending silicon characterization.
113 The Intel® Quartus® Prime software automatically selects the appropriate slew rate depending on the configured data rate or functional mode.
114 This specification pertains to Hyper Memory Cube.
115 Intel recommends a VOD ranging from 31 to 17.
116 500 ps is not supported for all configurations and depends upon the Master CGB placement.
