Overview
The SN65LV1224B is a deserializer component from Texas Instruments, designed to work in conjunction with the SN65LV1023A serializer as part of a 10-bit serdes chipset. This chipset is engineered to transmit and receive serial data over LVDS (Low-Voltage Differential Signaling) differential backplanes. The system supports parallel word rates from 10 MHz to 66 MHz, translating to serial data rates between 120 Mbps and 792 Mbps payload encoded throughput, including overhead.
The device is characterized for operation over an ambient air temperature range of –40°C to 85°C, making it suitable for industrial applications. It features a synchronization mode that allows for faster lock establishment and includes a lock indicator for monitoring the synchronization status.
