Data Sheet

Zarlink Semiconductor Inc.
AC Electrical Characteristics are over recommended operating conditions, unless otherwise stated.
Typical figures are nominal values and are for design aid only: not guaranteed and not subject to production testing.
*Notes:
1. Both mark and space have the same amplitude.
2. Tip/Ring signal level. Input op-amp configured to 0dB gain at Vdd=5V+/-10%, -3.5dB at Vdd=3V+/-10%.
3. Band limited random noise (200-3400Hz). Present when FSK signal is present. Note that the BT band is 300-3400Hz, the Bellcore
band is 0-4kHz.
4. dBV - Decibels above or below a reference voltage of 1 Vrms. 0 dBV = 1 Vrms.
5. dBm - Decibels above or below a reference power of 1 mW into 600 ohms. 0 dBm = 0.7746 Vrms.
Electrical characteristics are over recommended operating conditions, unless otherwise stated.
