71 / 144 page  MPC8548E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 6 Freescale Semiconductor 71 PCI Express TTX-IDLE-MIN Minimum time spent in electrical idle 50 — UI Minimum time a transmitter must be in electrical idle utilized by the receiver to start looking for an electrical idle exit after successfully receiving an electrical idle ordered set TTX-IDLE-SET-TO-IDLE Maximum time to transition to a valid electrical idle after sending an electrical idle ordered set — — 20 UI After sending an electrical idle ordered set, the transmitter must meet all electrical idle specifications within this time. This is considered a debounce time for the transmitter to meet electrical idle after transitioning from L0. TTX-IDLE-TO-DIFF-DATA Maximum time to transition to valid TX specifications after leaving an electrical idle condition — — 20 UI Maximum time to meet all TX specifications when transitioning from electrical idle to sending differential data. This is considered a debounce time for the TX to meet all TX specifications after leaving electrical idle RLTX-DIFF Differential return loss 12 — — dB Measured over 50 MHz to 1.25 GHz. See Note 4. RLTX-CM Common mode return loss 6 — — dB Measured over 50 MHz to 1.25 GHz. See Note 4. ZTX-DIFF-DC DC differential TX impedance 80 100 120 Ω TX DC differential mode low impedance ZTX-DC Transmitter DC impedance 40 — — Ω Required TX D+ as well as D– DC impedance during all states LTX-SKEW Lane-to-lane output skew — — 500 +2 UI ps Static skew between any two transmitter lanes within a single Link CTX AC coupling capacitor 75 — 200 nF All transmitters shall be AC coupled. The AC coupling is required either within the media or within the transmitting component itself. See note 8. Table 52.
