GX3290
290 x 290 3.5Gb/s Crosspoint Switch with Trace Equalization and Output
De-emphasis
Key Features
• 290 x 290 crosspoint switch architecture supporting
broadcast and multi-cast modes
• Supports all data rates up to 3.5Gb/s
• Low power consumption: 34.25W typical (all channels
active)
• Sophisticated, dynamic on-chip power management
control
• Independent, programmable input trace equalization
to reduce deterministic jitter (ISI)
• Independent, programmable output de-emphasis for
driving long board traces
• High-speed, video-optimized control for multi-format
applications
• Built-in system test features with on-chip PRBS
generators and analyzers
• 2.5V analog core voltage, 1.8V digital core voltage
• Input and output voltages support either 1.2V, 1.8V or
2.5V CML
• JTAG-controlled boundary scan
• Selectable parallel/serial host interface
• 50mm x 50mm BGA (2377 ball)
• Operating temperature range: 0°C to +85°C
• RoHS compliant
Applications
Large m x n cascaded routers/switch fabrics for:
• Professional broadcast applications
• Enterprise and carrier applications
• High-speed automated test equipment
• 10GbE and InfiniBand networks
Description
The GX3290 is a low-power, high-speed 290 x 290
crosspoint switch, with robust signal conditioning circuits
for driving and receiving high-speed signals through
backplanes.
The device typically consumes 34.25W of power with all
channels operational, and features sophisticated,
dynamically scalable power management. Unused
portions of the core are automatically turned off without
affecting the operation of the remaining channels.
The signal conditioning features of the GX3290 include
per-input programmable equalization and per-output
programmable de-emphasis. The input equalizer removes
ISI jitter—typically caused by PCB trace losses—by
opening the input data eye in applications where long PCB
traces are used. There are four settings available for the
input equalizer, allowing flexibility in adjusting the
equalization level on a per-input basis.
Output de-emphasis capability provides a boost of the
high-frequency content of the output signal, such that the
data eye remains open after passing through a long
interconnect of PCB traces and connectors. There are four
de-emphasis settings that can be enabled on a per-output
basis.
Two integrated programmable pattern generators, and two
pattern checkers are provided to assist in system test and
configuration.
The pattern generators can each be routed to any output of
the device without impacting the normal operation of any
other channel. Any input can be routed to each of the
pattern checkers.
The chip features eight independent strobe inputs,
UPDATE_EN[7:0], which are used to determine the timing
of the output updates. Any output can be linked to any
strobe.
