Desired Configuration
Quick Status Interface
The LXT1000 provides an additional Quick Status Interface for link-state monitoring. The
LXT1000 sends out 32 bits (16 data bits, 16 signature bits) of continuous information about the
current link state on the Quick Status data ball (QSTAT). Utilizing this single ball allows the MAC
to be constantly aware of what operations the PHY is performing. A separate, 25 MHz clock input
line (QCLK) provides synchronization for the data ball. Thus, an ASIC can monitor multiple PHY
devices using a single clock.
