Overview
The SN65LV1224BMDBREP, produced by Texas Instruments, is part of a 10-bit serializer/deserializer (serdes) chipset that includes the SN65LV1023A serializer and the SN65LV1224B deserializer. This chipset is designed to transmit and receive serial data over LVDS (Low-Voltage Differential Signaling) differential backplanes or unshielded twisted pair (UTP) cables at clock speeds ranging from 10 MHz to 66 MHz. The device supports payload bandwidths from 100 Mbps to 660 Mbps, making it suitable for high-speed data transmission applications.
The chipset is characterized by its extended temperature performance from –55°C to 125°C, low power consumption, and robust synchronization capabilities. It is pin-compatible with the DS92LV1023/DS92LV1224 and offers enhanced product-change notification and qualification pedigree in accordance with JEDEC and industry standards.

The operating temperature range is from –55°C to 125°C.
- What are the supported clock speeds for this chipset?
The chipset supports clock speeds from 10 MHz to 66 MHz.
- What is the typical power consumption of the SN65LV1224BMDBREP at 66 MHz?
The typical power consumption is less than 450 mW at 66 MHz.
- Does the SN65LV1224BMDBREP require external components for PLL operation?
No, it does not require external components for PLL operation.
- How does the synchronization mode work in the SN65LV1224BMDBREP?
The synchronization mode allows for faster lock times by generating SYNC patterns internally when SYNC1 or SYNC2 is held high for at least 6 clock cycles.
- What are the available package types for the SN65LV1224BMDBREP?
