In an AC-coupled link, the AC-coupling capacitor blocks the transmitter common-mode voltage. You can AC-couple the receiver to a transmitter. Signal detect is also compliant to SATA/SAS protocol up to 3 Gbps support. Signal detect is compliant to the threshold voltage and detection time requirements for electrical idle detection conditions as specified in the PCI Express Base Specification 2.0 for Gen1 and Gen2 signaling rates. The circuitry requires the input data stream to be 8B/10B-coded. The detection circuitry has a hysteresis response that asserts the status signal only when a number of data pulses exceeding the threshold voltage are detected and deasserts the status signal when the signal level below the threshold voltage is detected for a number of recovered parallel clock cycles. Senses if the signal level present at the receiver input is above or below the threshold voltage that you specified. A higher impedance setting reduces current consumption from the on-chip biasing circuitry. RX V CM is tri-stated when you use external termination.Ĭontrols the impedance of V CM. However, you must implement off-chip biasing circuitry to establish the required RX V CM level. You can disable OCT and use external termination. The termination resistance is adjusted by the calibration circuitry, which compensates for PVT. When you disable OCT, you must implement off-chip biasing circuitry to establish the required RX V CM level. The circuitry is available only if you enable OCT. Provides equal boost to the received signal across the frequency spectrum.Įstablishes the required receiver common-mode voltage (RX V CM) level at the receiver input. The amount of the high-frequency boost required at the receiver to overcome signal attenuation depends on the loss characteristics of the physical medium. Variation in the signal frequency response that is caused by attenuation leads to data-dependent jitter and other ISI effects-causing incorrect sampling on the input data at the receiver. The physical transmission medium can be represented as a low-pass filter in the frequency domain. Programmable Continuous Time Linear Equalization (CTLE)īoosts the high-frequency components of the received signal, which may be attenuated when propagating through the transmission medium.
