Differential I/O Standards | Receiver Input Waveforms
Transmitter Output Waveforms |
fHSCLK | Left and right PLL input clock frequency. |

|
RL | Receiver differential input discrete resistor (external to the Arria V GZ device). |
SW (sampling window) | Timing Diagram—the period of time during which the data must be valid in order to capture it correctly. The setup and hold times determine the ideal strobe position within the sampling window, as shown:
|
Single-ended voltage referenced I/O standard | The JEDEC* standard for SSTL and HSTL I/O defines both the AC and DC input signal values. The AC values indicate the voltage levels at which the receiver must meet its timing specifications. The DC values indicate the voltage levels at which the final logic state of the receiver is unambiguously defined. After the receiver input has crossed the AC value, the receiver changes to the new logic state. The new logic state is then maintained as long as the input stays beyond the DC threshold. This approach is intended to provide predictable receiver timing in the presence of input waveform ringing: Single-Ended Voltage Referenced I/O Standard |
tC | High-speed receiver and transmitter input and output clock period. |
TCCS (channel-to-channel-skew) | The timing difference between the fastest and slowest output edges, including tCO variation and clock skew, across channels driven by the same PLL. The clock is included in the TCCS measurement (refer to the Timing Diagram figure under SW in this table). |
