Description

The PM8610 SBI336 Bus Serializer (SBS) is a monolithic integrated circuit that implements conversion between a byte-serial 19.44 MHz SBI bus or 77.76 MHz SBI336 bus and a redundant

777.6 Mbit/s bit-serial 8B/10B-base SBI336S bus.

In TelecomBus mode, the SBS implements conversion between any 19.44 MHz TelecomBus or

77.76 MHz TelecomBus format and a redundant 777.6 Mbit/s bit-serial 8B/10B-base serial

TelecomBus format. In line with the bus conversion is a DS0 granular switch allowing any input

DS0 to be output on any output DS0. The redundant 777.6 Mbit/s serial interfaces can be disabled

and a byte-wide SBI336 bus can be enabled in its place with all the DS0 level switching

capabilities.
