Available in a 16-pin small outline package, it eliminates the need for an analog front end (AFE), an isolation transformer, relays, opto-isolators, and a 2- to 4-wire hybrid. The Si3016 dramatically reduces the number of discrete components and cost required to achieve compliance with global regulatory requirements. The Si3016 interfaces directly to a Silicon Laboratories integrated DAA system-side interface.

Test Circuit for Loop Characteristics Rev. 0.44 5 5 Page Si3016 Analog Output Figure 7 illustrates an optional application circuit to support the analog output capability of the DAA system-side module for call progress monitoring purposes. The ARM bits in Register 6 allow the receive path to be attenuated by 0, –6, or –12 dB. The ATM bits, which are also in Register 6, allow the transmit path to be attenuated by –20, –26, or –32 dB. Both the transmit and receive paths can also be independently muted. AOUT C2 R3 C1 C6 +5 V 36 +5 2– 4 R1 C3 C4 + C5 R2 Speaker Figure 7.
