Rainbow Electronics DS92LV010A - Manual

DS92LV010A
Bus LVDS 3.3/5.0V Single Transceiver
General Description
The DS92LV010A is one in a series of transceivers designed
specifically for the high speed, low power proprietary bus
backplane interfaces. The device operates from a single
3.3V or 5.0V power supply and includes one differential line
driver and one receiver. To minimize bus loading the driver
outputs and receiver inputs are internally connected. The
logic interface provides maximum flexibility as 4 separate
lines are provided (DIN, DE, RE, and ROUT). The device
also features flow through which allows easy PCB routing for
short stubs between the bus pins and the connector. The
driver has 10 mA drive capability, allowing it to drive heavily
loaded backplanes, with impedance as low as 27 Ohms.
The driver translates between TTL levels (single-ended) to
Low Voltage Differential Signaling levels. This allows for high
speed operation, while consuming minimal power with re-
duced EMI. In addition the differential signaling provides
common mode noise rejection of
± 1V.
The receiver threshold is ± 100mV over a ± 1V common
mode range and translates the low voltage differential levels
to standard (CMOS/TTL) levels.
