11.0 The LED Interface
11.1 LED Interface
The MDS212 LED interface supports the status per port in a serial stream that may be daisy-chained to connect
two MDS212 chips. Daisy-chaining greatly reduces the pin count and number of board traces routed from the
Physical Layer to the LEDs, thus simplifying system design and reducing overall system cost. For a large port
configuration such as the 24 in the MDS212, a large number of LED signals is needed, which may induce noise and
layout issues in the system. The LED information is transmitted in a frame-structured format with a synchronization
pulse at the start of each frame.
Figure 15 - LED Interface Connections
To provide the port status information from our MDS212 chips via a serial output channel, five additional
pins are required.
LE_CLKO - at 12.5 MHz
LE_SYNCI/O - a sync pulse -- defines the boundary between frames
LE_DI/O - acontinuous serial stream of data for all status LEDs which repeat once every frame time
A low cost external device (i.e. a 44-pin FPGA-like device) decodes the LED framed data and drives the LED array
for display. This device may be customized for different system configurations.
