IDT72V73273 3.3V TIME SLOT INTERCHANGE
DIGITAL SWITCH WITH RATE MATCHING 32,768 x 32,768 CHANNELS
MICROPROCESSOR INTERFACE
The IDT72V73273’s microprocessor interface looks like a standard RAM
interface to improve integration into a system. With a 16-bit address bus and
a16-bitdatabusallmemoriescanbeaccessed. UsingtheTSImicroprocessor
interface, reads and writes are mapped into Data and Connection memories.
By allowing the internal memories to be randomly accessed, the controlling
microprocessor has more time to manage other peripheral devices
andcanmoreeasilyandquicklygatherinformationandsetuptheswitchpaths.
Table 1 shows the mapping of the addresses into internal memory blocks. In

MEMORY MAPPING
Theaddressbusonthemicroprocessorinterfaceselectstheinternalregisters
and memoriesoftheIDT72V73273.Themostsignificantbitoftheaddressselect
between the registers and internal memories. See Table 1 for mappings.
Asexplainedintheinitializationsections,aftersystempower-up,theTDRSR
and RDRSR, should be programmed immediately to establish the desired
switchingconfiguration.
The data in the Control Register consists of the Software Reset, RX/TX
Bypass, Output Enable Polarity, All Output Enable, Full Block Programming,
BlockProgrammingData,BeginBlockProgrammingEnable,ResetConnection
Memory LOW in Block Programming, Output Standby, and Memory Select.
SOFTWARE RESET
The Software Reset serves the same function as the hardware reset. As
with the hard reset, the Software Reset must also be set HIGH for 20ns before
bringingtheSoftwareResetLOWagainfornormaloperation. OncetheSoftware
Reset is LOW, internal registers and other memories may be read or written.
During Software Reset, the microprocessor port is still able to read from all
internal memories. The only write operation allowed during a Software Reset
istotheSoftwareResetbitintheControlRegistertocompletetheSoftwareReset.
CONNECTION MEMORY CONTROL
If the ODE pin and the Output Standby bit are LOW, all output channels will
be in three-state. See Table 2 for detail.
If MOD2-0 of the Connection Memory HIGH is 1-0-0 accordingly, the output
channel will be in Processor Mode. In this case the lower eight bits of the
Connection Memory LOW are output each frame until the MOD2-0 bits are
changed. If MOD2-0 of the Connection Memory HIGH are 0-0-1 accordingly,
the channel will be in Constant Delay Mode and bits 14-0 are used to address
a location in Data Memory. If MOD2-0 of the Connection Memory HIGH are
0-0-0, the channel will be in Variable Delay Mode and bits 14-0 are used to
addressalocationinDataMemory.IfMOD2-0oftheConnectionMemoryHIGH
are 1-1-1, the channel will be in High-Impedance mode and that channel will
be in three-state.
RX/TX INTERNAL BYPASS
When the Bypass bit of control registers is 1, all RX streams will be “shorted”
toTX ineffectbypassingallinternalcircuitryoftheTSI. Thiseffectivelysetsthe

input to the TX output making the TSI “invisible”.
INITIALIZATION OF THE IDT72V73273
Afterpowerup,thestateoftheConnectionMemoryisunknown. Assuch,the
outputs should be put in High-Impedance by holding the ODE pin LOW. While
theODEisLOW,themicroprocessorcaninitializethedevicebyusingtheBlock

Once the device is configured, the ODE pin (or Output Standby bit depending
on initialization) can be switched to enable the TSI switch.
