QS74FCT863BTQ Datasheet The Intel IXP425 network processor family meets the requirements of next-generation broadband applications by integrating a unique distributed processing architecture that features the performance of the Intel XScale core and three Network Processor Engines (NPEs). The combination of the four high- performance processors provides tremendous processing power and enables wire-speed performance at both the LAN and WAN ports. QS74FCT863BTQ Price
QS74FCT863BTQ on stock The Transmitter has a differential input and an open collec- tor output current driver. The differential input common mode voltage is established by the CTI and should not be altered by external circuitry. The transformer coupling of TX+ will satisfy this condition. The driver meets all IEEE 802.3/Ethernet Specifications for signal levels. Controlled rise and fall times (25 ns V +5 ns) minimize the higher harmonic components. The rise and fall times are matched to minimize jitter. The drive current levels of the DP8392B meet the tighter recommended limits of IEEE 802.3 and are set by a built-in bandgap reference and an external l % re- sistor. An on chip isolation diode is provided to reduce the Transmitter's coax load capacitance. For Ethernet compati- ble applications, an external isolation diode (see Figure 4 ) may be added to further reduce coax load capacitance. In Cheapernet compatible applications the external diode is not required as the coax capacitive loading specifications are relaxed.
