The SP337EUCY-L is a single channel, low-voltage differential signaling (LVDS) differential line driver and receiver. It interfaces between the 1.2V digital logic of a System-on-Chip (SoC) microprocessor and the digital logic of another SoC, typically over a straight line, twisted pair, shielded cable, or optical link. It includes two LVDS line drivers and two LVDS line receivers, providing full duplex communication on one differential pair.

The SP337EUCY-L is designed for applications such as digital video, serial communications, remote sensing, industrial control, and automation. It is ideal for applications where low voltage and low power consumption is required and where a small form factor of space is needed due to its integrated design. With its onboard ESD protection, it is also well suited for applications involving harsh environments. The transmitter and receiver sections can each handle data rates up to 540 Mbps with —3 dB bandwidths of 600 MHz, while consuming only 15 mW at 3.3V.

The transmitter section of the SP337EUCY-L features two differential line drivers which output complementary LVDS signals differentially on one pair and one open-drain output which functions as a bus-hold signal. The receivers incorporate two LVDS line receivers which accept CML or LVTTL input levels. The differential receiver inputs feature 50Ω on-chip termination resistors controlled by the mode select pin. A latch-up protected CMOS input can detect logic-high or logic-low levels on the differential receiver inputs to initiate wakeup, system reset, or other required conditions.

SP337EUCY-L reduces cost and complexity by using only a single supply voltage of 3.3V. This integrated solution allows shrinking form factor without losing performance. The device also features built-in ESD protection circuitry and thermal shutdown to prevent damage from excessive power dissipation or over-temperature. The on-chip termination resistors and differentiation circuit provide superior signal integrity and reduce EMI, making the device well suited for applications where noise immunity is important.

SP337EUCY-L has been designed to operate in the temperature range of -40°C to +105°C and has been tested to meet Automotive Electronics Council (AEC) qualified stress tests. This makes the device ideal for applications in automotive and other industries requiring a rugged solution. The device is available in an 8-pin SOIC package and is pin compatible with its predecessors, the SN65LVDS and SP309EUC.

In conclusion, the SP337EUCY-L is a single channel, low voltage differential signaling (LVDS) driver and receiver designed for applications such as digital video, serial communications, remote sensing, industrial control, and automation. It integrates two LVDS line drivers and two LVDS line receivers, providing full duplex communication on one differential pair and a bus-hold signal output. It supports data rates up to 540 Mbps, low power consumption of 15 mW at 3.3V, and a temperature range of - 40°C to +105°C. The integrated design of the SP337EUCY-L reduces cost and complexity and provides superior signal integrity and EMI reduction, making it the ideal solution for applications where noise immunity is important.
