Specifications of PEF80902HV11XT

• Lead Free Status / Rohs Status: Compliant

New Features
• Optional use of transformers with non-negligible resistance corresponding to up to
• Inputs accept 3.3V and 5V
• I/O (open drain) accepts pull-up to 3.3V
• Pin compatible with Q-SMINT
• LEDs indicating Loopback 2 and activation status
• Lowest power consumption due to
• 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
• No integrated hybrid is provided by the T-SMINT
• Auxiliary IOM
• SRA (capacitive receiver coupling is not suited for S-feeding)
• NT-Star with star point on the IOM

– 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
always required, which consists of only two additional resistors as compared to an
integrated hybrid, but allows for more flexibility in board design.
Pull-ups to 5V must be avoided. A so-called ’hot-electron-effect’ would lead to long term degradation.
