Using Multiple VSC7216s in Parallel
Multiple VSC7216s can be used in parallel to form wider bus widths. In order for word alignment to
function correctly across multiple devices, each transmit channel’s input data must be transmitted on a common
clock, and each receive channel’s output data must also be aligned to a common word clock.
Receiver State Machine
Each channel contains a Loss of Synchronization State Machine (LSSM) which is responsible for detecting
and handling loss of bit, channel, word and word clock synchronization in a controlled manner.
Loopback Operation
Loop back control pins, LBENn(1:0), are provided in each channel to internally loopback data paths for
on-chip diagnosis. Both serial and parallel loopback functions are provided.
Built-In Self Test Operation
Built-In Self Test operation is enabled when the BIST input is HIGH, which causes TMODE(2:0) to be
internally set to 000. Upon entering BIST mode, the transmitter will issue a Word Sync Sequence in order to
recenter the elasticity buffers in the receive channel. Then each transmitter repeatedly sends a simple 256-byte
incrementing data pattern (prior to 8B/10B encoding) followed by three IDLE characters (K28.5). Each receiver
monitors incoming data for this pattern and indicates if any errors are detected. Correct reception of the pattern
is reported on each receiver’s TBERRn output, a LOW means the pattern is being received correctly and a
HIGH means that errors are detected.
Compatibility with VSC7214 and VSC7211
Care has been taken in the functional definition of the VSC7216 to be sure that it is compatible with the
VSC7211 and VSC7214 at the serial link level, and that the transmitter and receiver low-speed interfaces have
compatible modes of operation. It is strongly recommended that the VSC7216 not be connected in any way
through the WSO and/or WSI pins to a VSC7211 or VSC7214.
Serial Link Compatibility
The VSC7216 uses the same Fibre Channel 8b/10b encoding scheme and the same Word Sync Sequence
used in the VSC7211 and VSC7214. The only difference in serial link operation is that the VSC7211 and
VSC7214 require four consecutive identically-aligned Comma patterns to set the character framing boundary,
while the VSC7216 requires a single Comma.
Parallel Interface Compatibility
In general the VSC7216 low-speed parallel interfaces can be configured so that there are input and output
signals that are compatible with their VSC7211 and VSC7214 counterparts.
