The SN65LV1023A serializer and SN65LV1224B deserializer comprise a 10-bit serdes chipset designed to transmit and receive serial data over LVDS differential backplanes at equivalent parallel word rates from 10 MHz to 66 MHz. Including overhead, this translates into a serial data rate between 120-Mbps and 792-Mbps payload encoded throughput. Upon power up, the chipset link can be initialized via a synchronization mode with internally generated SYNC patterns or the deserializer can be allowed to synchronize to random data. By using the synchronization mode, the deserializer establishes lock within specified, shorter time parameters. The device can be entered into a power-down state when no data transfer is required. Alternatively, a mode is available to place the output pins in the high-impedance state without losing PLL lock. The SN65LV1023A and SN65LV1224B are characterized for operation over ambient air temperature of -55°C to 125°C.

The SN65LVCP15 is a high performance serial link mux for use in Fibre Channel (1.0625 Gb/s), Gigabit Ethernet (1.25 Gb/s), and other high speed interface applications. A common application involves a serializer/deserializer (SerDes), such as the TLK2201B, which would normally be connected to the IN± and OUT± ports in order to provide duplicate set of links on the IN0/OUT0 and IN1/OUT1 ports. This type of application is often used to implement high speed test ports that can be monitored without affecting the serial data stream of the application. A popular application is in Line Cards, that use serial links from a SerDes like TLK2201B (SLLS585), where the SN65LVCP15 provides redundant, hot-swappable links to redundant Switch Fabric Cards. During normal operation, IN is sent to both OUT0 and OUT1 whose buffers are enabled when OE0 and OE1 are HIGH. OUT0 can select between IN and IN1. OUT1 can select between IN and IN0. OUT can select between IN0 and IN1. In Link Replicator applications, such as the Line Card to Switch Card links, IN is transmitted to both OUT0 and OUT1 which either IN0 or IN1 is selected at OUT. In host Adapter applications, IN goes to OUT0 (an internal connector) which returns data and IN0. IN0 is looped to OUT1 (an external connector) which returns data on IN1 and then back to the SerDes on OUT.

Common applications are redundancy switching, signal buffering, or performance improvements on legacy backplane hardware. The SN65LVCP40 combines a pair of 1:2 buffers with a pair of 2:1 multiplexers (mux). Selectable switch-side loopback supports system testing.
