PI90LV019
Single Bus LVDS Transceiver
Features
Description
• Balanced Output Impedance
• Light Bus Loading: 5pF typical
• Glitch-freepowerup/down(DriverDisabled)
• High Signaling Rate Capability: >500 Mbps
• Driver:
ThePI90LV019,differentiallinedriverandreceiver(transceiver),
is compliant to IEEE1596.3 SCI and ANSI/TIA/
EIA-644LVDS standards.Thelogicinterfaceprovidesmaximum
flexibilityresultingfromfourseparatelinesthatareprovided: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.
– ±350mVDifferentialSwinginto:
– 100-ohmload(PI90LV019)
• Receiver:
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
rejectionof±1V.
– Accepts±50mV(min.)DifferentialSwingwithupto2.0V
ground potential difference
– Propagation Delay of 3.3ns typ.
– LowVoltageTTL(LVTTL)Outputs
– Open, Short, and Terminated Fail Safe
• BusterminalESDexceeds9kV
• IndustrialTemperatureOperation(–40°Cto+85°C)
• Packaging:(Pb-free&Greenavailable)

Note:
Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Notes:
1. “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not
meant to imply that the devices should be operated at these limits. The table of “Electrical Characteristics” specifies conditions
of device operation.
2. All currents into device pins are positive, all currents out of device pins are negative. All voltages are referenced to ground
except: V
V , V , and V unless otherwise specified.
