IP108A Octal 10100 Fast Ethernet Transceiver

The IP108Ais a highly integrated octal PHY transceiver for 10Base-T,100Base-TX and 100Base-FX Fast Ethernet applications. This device isimplemented with advanced 0.18um CMOS process technology for lowpower consumption. For the high port count switch design such as 16or 24 or 32-port, the IP108Acan simplify the system design and ensure the targeted performance..IP108Acan be programmed to operate in various modes through eitherhardware (hardware strapping pin) or software control (registerssetting via SMI). It also supports SMII and SS-SMII interface to MACcontroller to reduce the pin- count.The IP108Acontains eight independent 10/100MPHY Transceiver and includes encoder, decoder, line driver, ADC, DAC,DSP and PLL circuits for each port. The IP108Aenters the Automatic Power Saving Mode to lower the powerconsumption once the link partner is disconnected. The IP108Ajust needs an external OSC or crystal as the clock source,simplifying the system design. Besides the features described above,the driving capability of IP108Acan be trimmed to minimize the EMI effect by the advanced slew ratecontrol technology.Feature :Integrates eight-port10Base-T, 100Base-TX and 100Base-FX transceivers in a singlechip.Flexible 8-port 100Base-FXconfiguration.Supports auto crossoverfunction and force MDIX function.Supports auto-negotiationfunction.Flexible functionalconfiguration through either pin setting or registerprogramming.Supports SMII and SS-SMIIinterfaces.Supports BaseLine Wander (BLW)compensation.Provides direct drive modeand serial data latch LED display mode.Embeds DSP-based PHYTransceiver technology to improve the cable driving performanceAdjustablecurrent driving capabilitiesAdjustableSMII/SS-SMII interface timingProvides power-on LEDdiagnostic functionPower supply: Selectable3.3V/1.95V for I/O 1.95V power supply for coreSupports Automatic PowerSaving (APS) ModeRequires only one externalclock sourceSupport Lead Free package(Please refer to the Order Information)
