RHFLVDS315
Rad-hard quad LVDS driver
Datasheet - production data
Guaranteed up to 300 krad TID
SEL immune up to 135 MeV.cm²/mg
SET/SEU immune up to 67 MeV.cm²/mg
Description
The RHFLVDS315 is a quad, low-voltage,
differential signaling (LVDS) driver specifically
designed, packaged, and qualified for use in
aerospace environments in a low-power and fast
point-to-point baseband data transmission
standard.
Ceramic Flat-16
The upper metallic lid is
electrically connected to ground
Operating at 3.3 V power supply, the
RHFLVDS315 operates over a controlled
impedance of 100-ohm transmission media that
may be printed circuit board traces, back planes
or cables.
Features
LVDS output
The circuit features an internal fail-safe function to
ensure a known state in case of floating input. All
pins have cold spare buffers to ensure they are in
CMOS input
Enable/Disable function with high-impedance
ANSI TIA/EIA-644 compliant
400 Mbps (200 MHz)
high impedance when V is tied to GND.
CC
Designed using ST's proprietary CMOS process
with specific mitigation techniques, the
RHFLVDS315 achieves “best in the class” for
hardness to total ionisation dose and heavy ions.
Cold spare on all pins
3.3 V operating power supply
4.8 V absolute rating
The RHFLVDS315 can operate over a large
temperature range of -55 °C to +125 °C and is
housed in a hermetic Ceramic Flat-16 package.
Output voltage: 350 mV on 100 Ω load
