Si3038
Functional Description
The Si3038 is an integrated chipset that provides a low-
cost, isolated, silicon-based MC’97-compliant interface
to the telephone line. The Si3038 complies with the
AC’97 2.1 specification and requires only a few low-cost
discrete components to achieve global PTT compliance.
The device implements Silicon Laboratories’ patented
ISOcap technology which offers the highest level of
integration by replacing an analog front end (AFE), an
isolation transformer, relays, opto-isolators, and a 2- to
4-wire hybrid with two 16-pin small outline packages
(SOIC).
The Si3038 chipset can be fully programmed to meet
international requirements and is compliant with FCC,
CTR21, JATE, and various other country-specific PTT
specifications as shown in Table 19. In addition, the
Si3038 has been designed to meet the most stringent
worldwide requirements for out-of-band energy,
emissions, immunity, lightning surges, and safety.
Typical Si3038 designs implement a dual layout (see
Figure 19) capable of two population options:
FCC Compliant Population—This population option
removes the external devices needed to support
non-FCC countries. The FCC/JATE DAA Si3036
chipset is used.
Globally Compliant Population—This population
option targets global DAA requirements. This Si3038
international DAA chipset is populated, and the
external devices required for the FCC-only
population option are removed.
