SN65LV1224BDB

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 -40°C to 85°C. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
