The LED_DATA stream provides data for 30 separate direct drive LEDs and allows three
LEDs per MAC port. The three LED pins outlined above are detailed in
Descriptions, on page
There are two modes of operation, each with its own separate LED decode mapping.
Modes of operation and LEDs are detailed in
Modes of Operation
Mode selection is accomplished by using bit 0 of the
This bit is globally selected and controls the mode of operation of all ports
and
Mode 0
This mode selects operations compatible with the SGS Thompson M5450 Led Display
Driver Device. This device converts the serial data stream, output by the IXF1110 MAC, into
30 direct-drive LED outputs. In this mode, the latch signal is not required. This mode is
selected by setting bit 0 of the
Mode 1
This mode selects operations compatible with TTL (74LS595) or HCMOS (74HC595) octal
shift registers. This device converts the serial data stream, output by the IXF1110 MAC, into
30 direct-drive LED outputs. In this mode the LED DATA, LED CLK and LED LATCH signals
are used. This mode is selected by setting bit 0 of the
LED Interface Signal Description
The IXF1110 MAC LED interface consists of three output signal pins that are 2.5 V CMOS
level pads.

Signal Description
LED_CLK: This signal is an output that provides a continuous clock
synchronous to the serial data stream output on the LED_DATA pin. This
clock has a maximum speed of 720 hz.
The behavior of this signal remains constant in all modes of operation.
LED_DATA: This signal provides the data, in various formats, as a serial bit
stream. The data must be valid on the rising edge of the LED_CLK signal.
In Mode 0, the data presented on this pin is TRUE (Logic 1 = High).
In Mode 1, the data presented on this pin is INVERTED (Logic 1 = Low).
LED_LATCH: This is an output pin and the signal is used only in Mode 1 as
the Latch enable for the shift register chain.
This signal is not used in Mode 0, and should be left unconnected.
