3 Description

The SN65LVDS179, SN65LVDS180, SN65LVDS050, and SN65LVDS051 devices are differential line drivers and receivers that use low-voltage differential signaling (LVDS) to achieve signaling rates as high as 400 Mbps (see Table 1). The TIA/EIA-644 standard-compliant electrical interface provides a minimum differential output voltage magnitude of 247 mV into a 100-Ω load and receipt of 100-mV signals with up to 1 V of ground potential difference between a transmitter and receiver.
