General Description
The VSC7216 is a quad 8-bit parallel-to-serial and serial-to-parallel transceiver chip used for high
bandwidth interconnection between busses, backplanes, or other subsystems. Four Fibre Channel and Gigabit
Ethernet compliant transceivers provide up to 8.32 Gb/s of duplex raw data transfer. Each channel can be
operated at a maximum data transfer rate of 1016Mb/s (8 bits at 127MHz) or a minimum rate of 784Mb/s (8 bits
at 98MHz). For the entire chip in duplex mode, the aggregate transfer rate is between 6.3Gb/s and 8.3Gb/s. The
VSC7216 contains four 8B/10B encoders, serializers, de-serializers, 8B/10B decoders and elastic buffers which
provide the user with a simple interface for transferring data serially and recovering it on the receive side. The
device can also be configured to operate as four non-encoded 10-bit transceivers.
Functional Description
Clock Synthesizer
Depending on the state of the DUAL input, the VSC7216 clock synthesizer multiplies the reference
frequency provided on the REFCLK input by 10 (DUAL is LOW) or 20 (DUAL is HIGH) to achieve a baud
rate clock between 0.98 and 1.27 GHz. The on-chip PLL uses a single external 0.1uF capacitor to control the
Loop Filter.
Transmitter Data Bus
Each VSC7216 transmit channel has an 8-bit input transmit data character, Tn(7:0), and two control inputs.
8B/10B Encoder
Each channel contains an 8B/10B encoder which translates the 8-bit input data on Tn(7:0) into a 10-bit
encoded data character.
Encoder Bypass Mode
When ENDEC is LOW the 8B/10B encoder is bypassed and a 10-bit input character Tn(9:0) is serialized
directly in each channel. This mode of operation is similar to a 10-bit interface commonly found in serializer/
deserializers for the Fibre Channel (i.e. VSC7125) and Gigabit Ethernet markets (i.e. VSC7135).
Word Sync Generation
The VSC7216 can perform channel alignment (also referred to as “word alignment” or “word sync”),
meaning that the four receive data output streams are aligned such that the same 4-byte word presented to the
four transmit channel inputs for serialization will be transferred on the receive channel parallel outputs.
Serializer
The 10-bit output from the encoder (or from the encoder input register if ENDEC is LOW) is fed into a
multiplexer which serializes the parallel data using the synthesized transmit clock. The least significant bit of
the 10B data is transmitted first. Each channel has both primary and redundant serial output ports.
