DS90CR215MTDX

The DS90CR215MTDX from Texas Instruments is a specialized interface component functioning as an LVDS transmitter. It converts 21 bits of CMOS/TTL data into three LVDS data streams, with a phase-locked transmit clock sent over a fourth LVDS link. This chipset supports data throughput up to 1.386 Gbps at a 66 MHz clock frequency, equivalent to 173 Megabytes/sec.

The device operates on a single +3.3V supply and is rated for an industrial temperature range of -40°C to +85°C. Its LVDS output features a low swing of 290 mV for reduced EMI and a common-mode range around +1.2V. The transmitter includes a PLL that requires no external components.

Designed for efficiency, the multiplexing of data lines significantly reduces cable size and complexity compared to traditional parallel buses. This reduction in conductors leads to system cost savings, smaller connector sizes, and reduced shielding requirements. The DS90CR215MTDX is housed in a compact 48-lead TSSOP package suitable for surface mounting.

Key electrical characteristics include a typical power consumption of less than 250 mW, with a power-down mode consuming less than 0.5 mW. The component also boasts an ESD rating of greater than 7 kV.
