DESCRIPTION
The LX5255 is a Low Voltage
Differential
(LVD)
designed to comply with the LVD
termination specification in the SPI-4
document. The LX5255 is specifically
designed for LVD only applications.
Because the LX5255 supports only
LVD, it has lower output capacitance
than multimode terminators such as
the LX5250.
The LX5255 utilizes an industry
standard
LVD
architecture.
individual high bandwidth drivers
maximize channel separation, reduce
channel-to-channel noise and cross
talk to insure Ultra320 performance.
When the LX5255 is enabled, the
Differential Sense (DIFSENS) pin
terminator
The
supplies a voltage between 1.2V and
1.4V. In application, the terminator
DIFFB input is connected to the system
DIFSENS line. If there are no single
ended or High Voltage Differential
(HVD) devices attached to the system,
the LVD output will be enabled. If the
DIFSENS line is LOW, indicating a
single ended device, the LX5255 output
will be HiZ. If the DIFSENS line is
HIGH, indicating a HVD device, the
LX5255 output will be HiZ.
The LX5255 has a TTL compatible
sleep/disable mode. Applying a logic
HIGH to the DISC pin puts the LX5255
in sleep mode. During sleep mode,
power dissipation is reduced to a meager
5μA while also placing all outputs and
the DIFSENS function in a HiZ state.
