DS92LV1021AMSA

The DS92LV1021AMSA from Texas Instruments is a 10-bit serializer designed for high-speed serial data transmission. It converts a parallel LVCMOS/LVTTL data bus into a single LVDS serial data stream, complete with an embedded clock. This device is capable of transmitting data over backplanes or cables at bandwidths up to 400 Mbps, making it suitable for applications requiring efficient data transfer.

The serializer features a 10-bit parallel interface, supporting 1 byte of data plus 2 control bits. It offers a programmable edge trigger on the clock and its Bus LVDS serial output is rated for a 27 Ohm load. The device operates over a voltage range of 3V to 3.6V and has an operating temperature range of -40°C to 85°C (TA).

Designed for ease of PCB layout with a flow-through pinout, the DS92LV1021AMSA comes in a compact 28-lead SSOP package. This packaging, combined with its serial data transmission capability, helps reduce cable, PCB trace count, and connector size, contributing to overall system cost reduction. The single differential pair output eliminates multi-channel skew issues.

Key features include a single differential pair for data transmission, eliminating clock-to-data and data-to-data skew. The device also includes a powerdown pin for reduced supply current when not in use and output pins that can be put into TRI-STATE for a high impedance state. The PLL can lock to frequencies between 16 MHz and 40 MHz.
