SN65LVDM051-Q1数据手册TI中文资料规格书

描述 Description

The SN65LVDM050, and SN65LVDM051 are differential line drivers and receivers that use low-voltage differential signaling (LVDS) to achieve signaling rates as high as 500 Mbps (per TIA/EIA-644 definition). These circuits are similar to TIA/EIA-644 standard compliant devices (SN65LVDS) counterparts, except that the output current of the drivers is doubled. This modification provides a minimum differential output voltage magnitude of 247 mV across a 50- load simulating two transmission lines in parallel. This allows having data buses with more than one driver or with two line termination resistors. The receivers detect a voltage difference of 50 mV with up to 1 V of ground potential difference between a transmitter and receiver.
The intended application of these devices and signaling techniques is point-to-point and multipoint, baseband data transmission over a controlled impedance media of approximately 100 of characteristic impedance. The transmission media may be printed-circuit board traces, backplanes, or cables.
The SN65LVDM050Q and SN65LVDM051Q are characterized for operation from –40°C to 125°C. Additionally, Q1 suffixed parts are qualified in accordance with AEC-Q100 stress test qualification for integrated circuits.
