Notes:
2. Measured at TIP and RING with 600
termination at 1 kHz, as shown in Figure 1.
3. With FULL = 1, the transmit and receive full scale level of +3.2 dBm can be achieved with a 600
ac termination, while
the transmit and receive level in dBm varies with reference impedance, the DAA will transmit and receive 1 dBV into all
reference impedances in “FULL” mode. With FULL2 = 1, the transmit and receive full scale level of +6.0 dBm can be
achieved with a 600
ac termination. In “FULL2” mode, the DAA will transmit and receive +1.5 dBV into all reference
impedances.
4. Receive full scale level produces –0.9 dBFS at SDO.
5. DR = 20 x log (RMS VFS/RMS VIN).+ 20 x log (RMS VIN/RMS noise). The RMS noise measurement excludes
harmonics. VFS is the 0 dBm full-scale level.
6. Measurement is 300 to 3400 Hz. Applies to both transmit and receive paths. VIN = 1 kHz, –3 dBFS, Fs = 10300 Hz.
7. When using the Si3010 line-side, the typical DR values will be approximately 10 dB lower.
8. THD = 20 x log (RMS distortion/RMS signal). VIN = 1 kHz, –3 dBFS, Fs = 10300 Hz.
9. When using the Si3010 line-side, the typical THD values will be approximately 10 dB higher.
10. DRCID = 20 x log (RMS VCID/RMS VIN) + 20 x log(RMS VIN/RMS noise). VCID is the 6 V full-scale level for the typical
application circuit in Figure 17. With the enhanced CID circuit, the VCID full-scale level is 1.5 V peak, and DRCID
increases to 62 dB.
11. Available on the Si3019 line-side device only.
