Data Sheet
New Features
• Reduced number of external components for external U-hybrid required
• Optional use of up to 2x20
• 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
• LED signal is programmable but can also automatically indicate the activation status
• Pin compatible with T-SMINT
• Priority setting (8/10) for off-chip HDLC controller
• Enhanced IOM -2 timeslot access and manipulation (SCOUT)
• MCLK can be disabled (SCOUT)
• External Awake (EAW)
• Optional: All registers can be read and written to via new Monitor channel concept
• Optional: Implementation of S-transceiver statemachine in software
• Indirect Addressing (SCOUT)
• Programmable strobes SDS1/2 are more flexible, e.g. active during several timeslots
• Power-on reset and Undervoltage Detection with no external components
• Lowest power consumption due to:
• 200 mW (INTC-Q: 295 mW) power consumption with random data over ETSI Loop
• 15 mW typical power consumption in power down (INTC-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)
(mode select via 1 bit)
– 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
2 (external loads on the S and U interface only and no additional external loads).
Pull-ups to 5 V must be avoided. A so-called ’hot-electron-effect’ would lead to long term degradation.
