Description
The PI90LV019, differential line driver and receiver (transceiver),
is compliant to IEEE1596.3 SCI and ANSI/TIA/
EIA-644LVDS standards. The logic interface provides maximum
flexibility resulting from four separate lines that are provided: DIN,
DE, RE, and ROUT. These devices also feature flow through which
allows easy PCB routing for short stubs between the bus pins and
the connector.
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 reduced EMI. In
addition the differential signaling provides common mode noise
rejection of ±1V.
