H.100/H.110 Interfaces and Time-Slot Interchangers
1 Product Overview
1.1 Features
I
Complete solution for interfacing board-level cir-
cuitry to the H.100 telephony bus
I
H.100 compliant interface; all mandatory signals
I
Programmable connections to any of the 4096 time
slots on the H.100 bus
I
Up to 16 local serial inputs and 16 local serial
outputs, programmable for 2.048 Mbits/s,
4.096 Mbits/s, and 8.192 Mbits/s operation per CHI
specifications
I
Programmable switching between local time slots,
up to 1024 connections
I
Subrate switching of nibbles, dibits, or bits
I
Backward compatible to T8100 through software
I
Programmable switching between local time slots
and H.100 bus, up to 512 (T8102, T8105 only)
connections
I
Choice of frame integrity or minimum latency
switching on a per-time-slot basis
— Frame integrity to ensure proper switching of
wideband data
— Minimum latency switching to reduce delay in
voice channels
I
On-chip phase-locked loop (PLL) for H.100, MVIP*,
or SC-Bus clock operation in master or slave clock
modes
I
Serial TDM bus rate and format conversion
between most standard buses
I
Optional 8-bit parallel input and/or 8-bit parallel
output for local TDM interfaces
I
High-performance microprocessor interface
— Provides access to device configuration regis-
ters and to time-slot data
— Supports both Motorola
nonmultiplexed and
Intel
multiplexed/nonmultiplexed modes
I
Two independently programmable groups of up to
12 framing signals each
I
Devices available in 0.25 micron technology
I
3.3 V supply with 5 V tolerant inputs and TTL-com-
patible outputs
I
Boundary-scan testing support
I
208-pin, plastic SQFP package
I
217-ball BGA package (industrial temperature
range)
1.2 Description
These products in the AmbassadorT8100 family pro-
vide a complete time-slot switch and an interface for
the H.100/H.110 time-division multiplexed (TDM)
buses. The T8100 family includes devices with hier-
archical switching as well as a capacity of up to 512
local to H.100 connections. The hierarchical switch-
ing allows up to 1024 local connections without using
H.100 bus bandwidth. The family also includes the
T8102 device for a low-cost solution in nonhierarchi-
cal systems.
All three TSI chips are backward compatible with the
bus standards MVIP-90 and Dialogics
§
SC-Bus, as
well as supporting the newer standards, H-MVIPand
ECTF H.100. Other features include a built-in PLL for
H.100, MVIP or SC-Bus clock operation in master or
slave clock modes and two independently program-
mable groups of up to 12 framing signals each. Pack-
aged in both a 208-pin SQFP and a 217-ball BGA,
the T8100 TSI devices provide an economic solution
for the computer telephony market.
