2. Hardware Design Reference
The Si2493/57/34/15/04 chipset family consists of a 24-
pin TSSOP or a 16-pin SOIC low-voltage modem device
(Si2493/57/34/15/04) and a 16-pin SOIC line-side DAA
device
telephone local loop (TIP and RING). This modem
solution is a complete hardware (controller-based)
modem that connects to a host processor through a
serial or parallel interface (parallel, PCM, and EEProm
interfaces are only available on the 24-pin TSSOP
package option)
Laboratories’ isolation capacitor technology, which uses
high-voltage capacitors instead of a transformer. This
isolation
telecommunications standards including FCC, CTR21,
JATE, and all known country-specific requirements.
Country, EMI/EMC, and safety test reports are
available.
salesperson or distributor for more details. Additional
features include programmable ac/dc termination and
ring impedance, on-hook and off-hook intrusion
detection,
monitoring, overcurrent detection, ring detection, and
the switch-hook function.

All required program and data memory is included in the
modem device. When the modem receives a software
or hardware reset, all register settings revert to the
default values stored in the on-chip program memory.
The host processor interacts with the modem controller
through AT commands used to change register settings
and control modem operation. Changing register
settings and controlling the modem is described in "3.
Software Design Reference" on page 21.
2.1. Modulations and Protocols
Tables 1 through 3 list the modulations, protocols,
carriers, and tones supported by the Si2493/57/34/15/
04 modem family. The Si2493 supports all modulations
and protocols from Bell 103 through V.92. The Si2457
supports all modulations and protocols from Bell 103
through V.90. The Si2434 supports all modulations and
protocols from Bell 103 through V.34. The Si2415
supports all modulations and protocols from Bell 103
through V.32bis. The Si2404 supports all modulations
and protocols from Bell 103 through V.22bis.
