New Features
Optional use of transformers with non-negligible resistance corresponding to up to
20
on the line sidePin Vref and the according external capacitor removed
Inputs accept 3.3V and 5V
I/O (open drain) accepts pull-up to 3.3V
1)
Pin compatible with Q-SMINT O (2nd Generation)
LEDs indicating Loopback 2 and activation status
Lowest power consumption due to
Low power CMOS technology (0.35μ)
Newly optimized low power libraries
High output swing on U- and S-line interface leads to minimized power consumption
Single 3.3 Volt power supply
185mW (NTC-T: 233mW) power consumption with random data over ETSI Loop 2.
15mW typical power consumption in power down (as NTC-T; NTC-Q: 28mW)
1.3
Not Supported are ...
No integrated hybrid is provided by the T-SMINT O. Therefore, an external hybrid is
always required, which consists of only two additional resistors as compared to an
integrated hybrid, but allows for more flexibility in board design.
Auxiliary IOM
2
interface
SRA (capacitive receiver coupling is not suited for S-feeding)
NT-Star with star point on the IOM
-2 bus (already not supported in NTC-T).
1)
Pull-ups to 5V must be avoided. A so-called
hot-electron-effect
would lead to long term degradation.
