Hot-selling and scarce VSC8574XKS-04 Telecom IC Ethernet 256-PBGA spot stock

Product Descriptions

The VSC8574-01 is a low-power, quad-port Gigabit Ethernet transceiver with four SerDes interfaces for  quad-port dual media capability. It also includes an integrated quad port two-wire serial multiplexer  (MUX) to control SFPs or PoE modules. It has a low electromagnetic interference (EMI) line driver, and  integrated line side termination resistors that conserve both power and printed circuit board (PCB) space.

The VSC8574-01 includes Microsemi’s IEEE 1588 timestamping solution with encapsulation support.  The device also includes dual recovered clock outputs to support Synchronous Ethernet applications.  Programmable clock squelch control is included to inhibit undesirable clocks from propagating and to  help prevent timing loops. The VSC8574-01 also supports a ring resiliency feature that allows a  1000BASE-T connected PHY port to switch between master and slave timing without having to interrupt  the 1000BASE-T link.
