Ag9900 - Ultra-miniature module for the Powered Device (PD)

The Ag9900 series PD modules pushes the boundaries of POE miniaturisation further than ever before, yet still offers all the features expected from Silvertel’s POE. This is the smallest package size available that is designed to extract power from a Cat5 cable, fully conforming to the 802.3af Power-over-Ethernet (PoE) standard and includes 1.5kV isolation, PoE signature and an integral DC to DC converter. The module provides a Class 0 signature.

Ag9900 offers a simple, ultra-small PoE solution using minimal external low cost components. External bridge rectifiers enable the device to be powered from midor end-span PSE, accepting power from either the spare or data pairs of the cable. An integrated optimised DC/DC converter operates over a wide input voltage range with high efficiency (up to 87%). Built-in protection against overloads and shortcircuits is also provided. The regulated DC output nominal voltage is easily adjusted using a simple pull up/down resistor.

Programmable LED Driver

The Ag201 module from Silvertel is a versatile, low-voltage DC input LED driver module. The flexible, feature-rich product is delivered in a tiny package.

Multiple values of programmable constant current output allow connection with a variety of LEDs. The module’s buck-boost DC-DC converter topology means the input voltage can be either higher or lower than the string (output) voltage, allowing for ease of design with a wide range of DC input voltage and LEDs.

Flexible communications arrangements are built in with options of both I2C and DALI. The simple addition of an external program resistor sets the module output current from the preset range. Minimal additional components are required to complete the design.

All this functionality is delivered in a package measuring 56 x 14 x 10 mm. The product has been designed as an easy-to-program modular solution that is simple to design into a variety of applications by virtue of its wide input range and flexible output current capabilities.

Fairmont Marketing has been appointed as distributor of Silvertel

Silvertel has designed and developed several Power over Ethernet (PoE) module ranges to suit different applications. Their PoE modules require minimal external components and all have built-in signature recognition and class programming which complies to the IEEE802.3af standard. For flexibility most PoE modules are available with different output voltages, all have output voltage offset adjustment, short circuit protection and thermal protection.

Silvertel's Subscriber Line Interface Circuit (SLIC) modules can be used for analog line interface applications, enabling signals to be transmitted and received from the telephone line, feed power to the line and monitors the line condition The SLIC modules are designed to provide a small, easy to use and low cost solution for ISDN Terminal Adaptors, Internet Telephony (VoIP), Computer Telephony Integration (CTI) Wireless Local Loop (WLL), Fixed Cellular Terminals (FCT), Fixed Wireless Terminals (FWT) and Small Office Home Office (SOHO) applications.

PSTN interfaces, also known as Trunk Interfaces, Foreign eXchange Office (FXO) circuit, Data Access Arrangements (DAA) and Central Office Interface Circuit (COIC). Silver Telecom PSTN modules that are suitable for a wide range of applications and meet the requirements of CTR21, FCC Pt.68, UL60950, AS NZ3260 and AS ACIF S043. Providing programmable d.c. mask, line and network impedance give PSTN modules the flexibility to be used in any market. On-Hook reception allows our modules to support Caller Line ID and by using transformer isolation this provides high common-mode rejection for use in ungrounded systems.

Silver Telecom's battery charger modules are designed for reducing power consumption and maximising rechargeable battery life. The modules have a wide input range and a high efficiency DC to DC converter. The charging voltage is controlled with a high accuracy and can be varied with temperature. The module also reports on the battery condition to eliminate unnecessary battery changes or unexpected battery failures. Different modules to cover Sealed Lead Acid (SLA) and Lithium Ion battery.
