LXT16706/16707
SerDes Chipset
Product Description
The Intel
LXT16706 and LXT16707 form a
high-performance Multiplexer/Demultiplexer
(MUX/DeMUX) chipset for use in SONET OC-192
and SDH STM 64 telecommunications systems,
Optical Transport Network (OTN) systems with
Forward Error Correction (FEC), submarine
systems, and fiber optic test equipment.
The Intel
LXT16706/07 chipset is manu-
factured using a well-proven SiGe BiCMOS
technology that offers the performance, stability,
and reliability customers require for optical
communication systems.
The devices are operated from a single +3.3V
or dual +1.8/+3.3V power supply. The chipset
has a low power dissipation of 1.7W (when
operated from a dual power supply).
The LXT16706 features an integrated Limiting
Amplifier (LIA) with low input sensitivity, a
Clock and Data Recovery unit (CDR) and a
1:16 DeMUX.
The LXT16707 features a 16:1 transmitter with
integrated clock generation, Phase Locked
Loop (PLL) circuits, and MUX. The high output
swing of the transmitter ensures compatibility
with a wide range of laser drivers.
The LXT16706/07 chipset features two
concepts for timing alignment of clock and
data signals coming from the framer. The first,
Dynamic Phase Alignment is based on inte-
grated PLLs to eliminate any skew between
clock and data signals between ASIC and MUX.
The continuous handling of round trip delay
variations by the source synchronous clocking
ensures easy external optimization of jitter. The
second is based on a 2-bit FIFO shift register
to ensure critical timing alignment between
clock and data signals.
In order to facilitate board design, the
LXT16706/07 chipset has been equipped with
bit flip and bit inversion. These features flip the
polarity and/or position of the individual pins to
enable flexible PCB routing.
The devices allow operation at any line rate
between 9.95 to 10.71Gbps. This provides
a flexible module with reduced design and
production costs.
