Data Sheet
New Features
• Reduced number of external components for external U-hybrid required
• Optional use of up to 2x20 resistors on the line side of the transformer (e.g. PTCs)
• Pin Uref and the according external capacitor removed
• Improved ESD (2 kV instead of <850 V)
• Inputs accept 3.3 V and 5 V
• I/O (open drain) accepts pull-up to 3.3 V
• Pin compatible with T-SMINT
• LED indicates Loopback 2 (LBBD)
• Power-on reset and Undervoltage Detection with no external components
• Lowest power consumption due to
• 200 mW (NTC-Q: 285 mW) power consumption with random data over ETSI Loop 2.
• 15 mW typical power consumption in power down (NTC-Q: 28 mW)

The Q-SMINT
significantly enhanced performance of the U-interface as compared to ETSI [1], ANSI
[2] and CNET [3] requirements is guaranteed:
Transparent transmission on 20kft AWG26 with a BER < 10
1)
– Low power CMOS technology (0.35µ)
– Newly optimized low power libraries
– High output swing on U- and S-line interface leads to minimized power
– Single 3.3 Volt power supply
Pull-ups to 5 V must be avoided. A so-called ’hot-electron-effect’ would lead to long term degradation.
