AM79C874VC

The AM79C874VC is one member of the AM79C874 family which designed as one kind of low power 10/100-TX/FX ethernet transceiver that delivers the dual benefits of CMOS low power consumption and small package size.It can receive and transmit data reliably at over 130 meters. It includes on-chip input filtering and output waveshaping for unshielded twisted pair operation without requiring external filters or chokes.

Features of the AM79C874VC are:(1)typical power consumption of 0.3 W;(2)sends/receives data reliably over cable lengths greater than 130 meters;(3)MII mode supports 100BASE-X and 10BASE-T;(4)7-wire (general purpose serial interface (GPSI)) mode supports 10BASE-T;(5)waveshaping-no external filter required;(6)full and half-duplex operation with full-featured auto-negotiation function;(7)MDIO/MDC operates up to 25 MHz;(8)automatic polarity detection;(9)built-in loopback and test modes;(10)single 3.3-V power supply with 5-V I/O tolerance;(11)12 mm x 12 mm 80-pin TQFP package;(12)support for indust-rial temperature(-40°C to +85°C).

The absolute maximum ratings of the AM79C874VC can be summarized as:(1)storage temperature:-55°C to +150°C;(2)ambient temperature under bias:-55°C to +150°C;(3)supply voltage:-0.5 V to +5.5 V;(4)voltage applied to any input pin:-0.5 V to VDD.If you want to know more information such as the electrical characteristics about the AM79C874VC,please download the datasheet in www.seekic.com or www.chinaicmart.com .
