Preliminary

TelecomBus Serializer for 2.5 Gbit/s Interconnect

PM5310

TBS

FEATURES

• Encodes data from the Incoming
parallel TelecomBus to a set of four
working, a set of four protection, and a
set of four auxiliary 777.6 Mbit/s LVDS
serial TelecomBus links with extended
8B/10B-based encoding.

• Decodes data from a set of four
working, a set of four protection, or a
set of four auxiliary 777.6 MHz LVDS
serial links with extended 8B/10B­based encoding to the Outgoing
TelecomBus stream.

• Provides capacity to carry an STS­12/STM-4 stream in each LVDS serial
TelecomBus link. Four links can be
aggregated to form an STS-48c/STM­16c stream.

• Provides capacity to carry an STS­12/STM-4 stream in each 8-bit bus of
the parallel TelecomBus stream. Four
8-bit buses can be aggregated to carry
an STS-48c/STM-16c stream.

• Provides redundant working,
protection and auxiliary transmit LVDS
serial TelecomBus streams and

redundant receive LVDS serial
TelecomBus streams for protection
switching purposes.

• Provides independent time-slot
interchange blocks on the Incoming
and Outgoing parallel TelecomBus
streams to allow arbitrary arrangement
of time-slots at STS-1 granularity.

• Supports redundant working/protection
time-space-time switch fabric.

• Supports through-traffic, drop-traffic
and protection switching in UPSR, 2­fibre BLSR and 4-fibre BLSR
applications (when used with the
PM5372 TSE).

• Uses extended 8B/10B-based line
coding protocol on the serial links to
provide transition density guarantee
and DC balance and to offer a greater
control character vocabulary than the
standard 8B/10B protocol.

• Provides encoding of TelecomBus
control signals at the multiplex section
termination (MST) point, high-order
path termination (HPT) point and low­order path termination (LPT) point.

• Provides optional PRBS generation for
each outgoing LVDS serial
TelecomBus data link for off-line link
verification.

• Provides PRBS detection for each 8-bit
bus on the Incoming parallel
TelecomBus stream.

• Provides PRBS detection for each
incoming LVDS serial TelecomBus
stream for off-line link verification.

• Provides optional PRBS generator for
each 8-bit bus on the outgoing parallel
TelecomBus stream.

• Provides in-service link verification by
optionally overwriting the B1 and E1
byte of each constituent STS-1/STM-0
with a unique software programmable
byte and its complement.

• Provides pins to coordinate updating of
the connection map of the time-slot
interchange blocks in the local device,
peer PM5310 TBS devices and
companion PM5372 TSE devices.

• Derives all internal timing from a single

77.76 MHz system clock.
