Post Amplifier
The KSZ8893FQL also includes a post amplifier. The post amplifier is intended for interfacing the output of the pre-
amplifier of the PIN diode module. The minimum sensitivity of the post amplifier is 2.5mVrms.
Power Management
The KSZ8893FQL features a per-port power down mode. To save power, a PHY port that is not in use can be powered
down via port control register, or via MIIM PHY register.
In addition, there is a full chip power down mode. When activated, the entire chip is powered down.
MDI/MDI-X Auto Crossover
To eliminate the need for crossover cables between similar devices, the KSZ8893FQL offers HP Auto MDI/MDI-X and
Micrel Auto MDI/MDI-X crossover. HP Auto MDI/MDI-X is the default.
The auto-sense function detects remote transmit and receive pairs and correctly assigns transmit and receive pairs for
the KSZ8893FQL device. This feature is extremely useful when end users are unaware of cable types, and also, saves
on an additional uplink configuration connection. The auto-crossover feature can be disabled through the port control
registers, or MIIM PHY registers.

Straight Cable
A straight cable connects an MDI device to an MDI-X device, or an MDI-X device to an MDI device. The following
diagram depicts a typical straight cable connection between a NIC card (MDI) and a switch, or hub (MDI-X).
