Data Sheet
DC Electrical Characteristics
†DC Electrical Characteristics are over recommended operating conditions, unless otherwise stated.
‡Typical figures are at 25°C and are for design aid only: not guaranteed and not subject to production testing.
AC Electrical Characteristics
†AC Electrical Characteristics are over recommended operating conditions, unless otherwise stated.
‡Typical figures are at 25°C and are for design aid only: not guaranteed and not subject to production testing.
*Notes:
1. OSC1 frequency at 3.579545 MHz ± 0.1%.
2. Tip/Ring or 4-wire side input signal level. Signal level is per tone.
3. ‘On Hook mode’: GS1 op-amp configured to 0 dB gain for Vdd=5V±10%, -4 dB (preliminary) for Vdd=3V±10%.
4. ‘Off Hook mode’: GS2 op-amp configured to 0 dB gain for Vdd=5V±10%, -4 dB (preliminary) for Vdd=3V±10%.
5. When the signal level difference between the upper and lower tones is within the twist limits.
6. Test condition is both tones have the same amplitude.

dBm = decibels above or below a reference power of 1 mW into 600 ohms. 0 dBm = 0.7746Vrms.
dBV = decibels above or below a reference voltage of 1 Vrms. 0 dBV = 1 Vrms.
