Features
• 16 PECL/CML fully differential
(back-terminated) outputs
• >2.5 Gb/s data bandwidth
per channel
• >40 Gb/s aggregate bandwidth
The TQ8025 is a non-blocking 16 x 16 digital crosspoint switch capable of
data rates greater than 2.5 gigabits per second per port. With a fully
differential internal data path and PECL/CML I/O, the TQ8025 offers an
extremely high data rate with exceptional signal fidelity. The use of fully
differential logic results in low crosstalk, jitter, and signal skew. The
TQ8025 is ideally suited for digital video, data communications,
telecommunication switching, and cross-connect applications.
The non-blocking architecture uses 16 fully independent 16:1 multiplexers
which allow each output port to be independently programmed to any input
port. The TQ8025 offers two programming options: a flexible port-by-port
option, and a fast configuration option.
Using the fast configuration option, all 16 switch ports are programmed
within 80ns by serially loading four 16-bit input port selection words. Two
output pins (RADD0,1) are provided to drive an external RAM
(n x 4 x 16 bits) used to store the switch configuration. An Autoconfigure
option automatically transfers the new configurations into the switch core.
Autoconfiguration occurs after the last input selection word is clocked into
the programming registers.
• Non-blocking architecture
• 80 ns configuration time
• Autonomous control of external
RAM for configuration data
• Low jitter and signal skew
• ±100 ps delay match (one input
to all outputs)
• Fully differential data path
• 132-pin MLC package with
heat spreader
Applications
• SONET OC-48 data path
• Double-speed Fibre Channel
• Hubs and routers
• High-definition video switching
• Parallel processing
Data integrity is maintained on all unchanged data paths for both the portby-port and fast configuration options.

RAM address; TTL output, tristate
Used to generate address 0-3 during configure load from RAM.
ADDREN

When low, enables RADD0:1; when high, forces RADD0:1 tristate.

READY
READY; open-drain output
LOAD
LOAD; TTL input
Indicates end of AUTOCONFIG or end of address LOAD cycle
when high. Reset low by RESET-, CONFIG low, or LOAD rising.
Requires external pullup to VCC.
For LDMODE=1, ADDREN=0: AUTOCONFIG=0, rising LOAD causes
ADDR0:1 to generate RAM addresses, then READY is asserted
after four clock ticks. For AUTOCONFIG=1, LOAD rising causes
ADDR0:1 to generate addresses, causing an internal CONFIG
to be generated, after which READY is asserted. For LDMODE=0,
see SAD0:3 and DAD0:3.
Used to load address contents of internal address registers.
Active LOW. Crosspoint will be configured within 4 ns
(objective) of CONFIG falling low.
When floated high, AD0-15 are used for configuration.
When tied low, SAD0-3 and DAD0-3 are used for configuration.
When AUTOCONFIG is disabled, and AD08-15 are ignored.
When LDMODE is low, specifies input address to be connected
to output port specified by DAD0:3. Latched by falling LOAD
(LDMODE=0).
When LDMODE is low, specifies output address to be connected
to input port specified by SAD0:3. Latched by falling LOAD
(LDMODE=0).
Power and ground pins.
VTT = GND for CML inputs; VTT = VCC – 2V for PECL inputs.
While low, programs all output ports to connect to input port 0.
Strobing CONFIG after reset restores user port programming
if device power was stable since last user programming and
during RESET–. Active low, Schmitt triggered.
