SI2404-D-GT - 2.4 kbit/s Global DAA Modem | Skyworks
MPN: SI2404-D-GT ✓ فعالSI2404-D-GT جائزہ
A modem IC converts digital data into an analog signaling format suitable for transmission over a communications channel, and a global DAA provides the interface between that modem and the line or external analog network. The SI2404-D-GT integrates these functions into one package, reducing the component count and board area required for conventional data-communication terminals, modem cards, and embedded communication modules.
The SI2404-D-GT supports six identified modulation and signaling protocols: V.21, V.22, V.23, V.29, Bell 103, and Bell 212A. Its nominal 2.4 kbit/s data rate makes it appropriate for legacy asynchronous and synchronous communications, terminal equipment, remote data access, and industrial systems that must interoperate with established modem standards rather than broadband data rates.
Housed in a 24-pin TSSOP package, the SI2404-D-GT is intended for surface-mount PCB assembly. The package provides a compact footprint for equipment where connector area and board height are constrained. Detailed electrical limits, interface timing, clock requirements, and line-side implementation guidance should be confirmed against the manufacturer datasheet before schematic capture.
Typical uses include legacy data-terminal equipment, point-of-sale systems, industrial data-collection terminals, embedded modem modules, and communications equipment bridging digital logic to analog lines. Designers can select the protocol configuration required by the connected network and use the integrated DAA to reduce the number of external interface components.
When laying out a PCB, follow the manufacturer pin-description and application schematics for power, ground, analog, and digital connections. Keep sensitive modem and DAA traces away from noisy switching paths, use a stable low-noise supply, and validate the completed interface against the target line standard. The 24-pin TSSOP outline requires careful escape routing between its closely spaced leads.
This product page consolidates the SI2404-D-GT data rate, supported protocols, package details, pin-access guidance, and same-family alternatives into a focused engineering reference. It also provides practical selection criteria for legacy modem and global DAA designs where a 2.4 kbit/s interface and 24-pin TSSOP integration are the decisive requirements.

عام استعمالات
SI2404-D-GT کے لیے موزوں ہے 6 ایپلیکیشنs: Legacy Data Terminal Equipment, Industrial Data Collection, Point-of-Sale Terminal, Embedded Modem Module, Remote Monitoring System, Telecommunications Test Equipment.
Legacy Data Terminal Equipment
The SI2404-D-GT fits legacy data-terminal equipment that connects a digital host to a 2.4 kbit/s communications channel. Its integrated modem and global DAA reduce the component count and PCB area required to implement V.21, V.22, V.23, V.29, Bell 103, or Bell 212A operation. The 24-pin TSSOP package supports compact surface-mount designs, while the multiple protocol options allow the same platform to address different line standards. Designers should configure the required protocol, verify timing and electrical limits in the manufacturer datasheet, and validate the complete line interface before production.

Industrial Data Collection
The SI2404-D-GT is appropriate for industrial data-collection equipment that relies on established 2.4 kbit/s modem protocols. Support for V.21, V.22, V.23, V.29, Bell 103, and Bell 212A provides flexibility when remote endpoints use different legacy modulation schemes. Integrating the modem and global DAA in one 24-pin TSSOP device reduces board space and simplifies the communications subsystem. The installation still requires careful review of line coupling, isolation, surge protection, grounding, and environmental requirements, because the communications channel may be exposed to industrial noise and transients.

Point-of-Sale Terminal
The SI2404-D-GT can support point-of-sale terminals that communicate through a 2.4 kbit/s modem rather than a modern broadband interface. The integrated global DAA provides a compact path between the modem circuitry and the external line, while six supported protocols improve compatibility with different backend systems. Its 24-pin TSSOP package is useful where the product enclosure has limited board area and requires surface-mount assembly. Product engineers must confirm protocol compatibility, transaction timing, line protection, and ESD requirements, and should use the manufacturer application implementation as the schematic and layout baseline.

Embedded Modem Module
The SI2404-D-GT fits embedded modem modules that must add legacy communications to a digital controller. Its 2.4 kbit/s modem and global DAA functions occupy a single 24-pin TSSOP footprint, simplifying assembly compared with a split modem and line-interface design. The protocol set supports V.21, V.22, V.23, V.29, Bell 103, and Bell 212A, allowing a common hardware platform to serve different installed-base requirements. Confirm the module's required data format, control signaling, clocking, line impedances, and supply limits against the manufacturer documentation before fixing the PCB design.

Remote Monitoring System
The SI2404-D-GT can be integrated into a remote monitoring system that sends low-bandwidth telemetry through an established 2.4 kbit/s modem network. Its support for six legacy protocols allows the monitoring equipment to interoperate with systems using V.21, V.22, V.23, V.29, Bell 103, or Bell 212A. The 24-pin TSSOP package keeps the radio and digital control sections compact, while the integrated global DAA reduces the external line-interface footprint. For field installations, add the required isolation and surge protection and verify EMC, temperature, and power-consumption requirements against the final enclosure.
تجویز کردہ
Telecommunications Test Equipment
The SI2404-D-GT is suitable for telecommunications test equipment that must emulate or communicate with legacy 2.4 kbit/s modem endpoints. The range of V.21, V.22, V.23, V.29, Bell 103, and Bell 212A protocols allows a tester to cover several modulation standards without changing the physical package. Combining the modem and global DAA in a 24-pin TSSOP supports compact instrumentation and daughterboard designs. Engineers should establish the exact test profile, line impedance, signal timing, and isolation architecture, then use the manufacturer application schematics to reproduce power and analog routing accurately.

ڈیزائن نوٹس
Build the footprint from the TSSOP-24 mechanical drawing rather than assigning a generic 24-pin land pattern. Confirm body width, lead pitch, toe length, and exposed-pad status against the ordered package. Keep the modem and global DAA power connections close to their decoupling components, and route the analog line-side region separately from switching nodes and digital clocks.
Do not treat a shared TSSOP-24 outline as proof that every SI2404 variant is electrically interchangeable. Before replacing the SI2404-D-GT, compare the complete pin-description table, supply limits, operating-temperature range, protocol behavior, timing requirements, and line-side interface. Pay particular attention to any ordering suffix that changes temperature grade, packing, or device revision.
Use the manufacturer application schematic to establish clocking, grounding, and separation between digital control signals and the analog communications interface. Route sensitive modem signals continuously over a stable ground reference, avoid running them beneath unrelated switching-current paths, and include test points for clock, data, control, and line signals so timing and noise can be checked during hardware validation.
