A feature comparison between the Si3018/10 and the Si3008 is presented in Table 106. This table is designed to
present a quick capability comparison to enable the selection of the best DAA chip for a particular design.
The Si3008 supports parallel handset off-hook/on-hook detection in both the on and off-hook modes. Loop current
is measured with 3.3 mA/bit resolution by the LCS bits. The LCS bits V loop current response is shown in
Figure 35, and the LCS transfer function is explained in Table 107. The DC I/V characteristic is illustrated in
Figure 36 and meets the requirements of the countries listed in Table 105. The Si3008 provides a ringer
impedance of approximately 5 M Ω and has an on-hook line monitor mode that supports Type 1, Type 2, and UK
Caller ID.
