SN65LVDS179DG4

高速差分线路驱动器和接收 HIGH-SPEED DIFFERENTIAL LINE DRIVERS AND RECEIVERS

DESCRIPON

The SN65LVDS179, SN65LVDS180, SN65LVDS050, and SN65LVDS051 are differential line drivers and receivers that use low-voltage differential signaling LVDS to achieve signaling rates as high as 400 Mbps. 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 50-mV signals with up to 1 V of ground potential difference between a transmitter and receiver.
