Specifications at -40°C are guaranteed by design and characterization.
Excluding I BIAS and I MOD . Input data is AC-coupled. TX_FAULT open, SHUTDOWN open.
Power-supply noise rejection (PSNR) = 20log 10 (V noise (on VCC ) / Δ V OUT ). V OUT is the voltage across the 15 Ω load when IN+
is high.
The minimum required voltage at the OUT+ and OUT- pins is +0.75V.
Guaranteed by design and characterization.
Tested with 00001111 pattern at 2.7Gbps.
DJ includes pulse-width distortion (PWD).
