Product Overview
The SN65LVDT41 is a Texas Instruments Signal_Chain device configured as a multi-channel LVDS transceiver. Its channel structure combines four LVDS drivers with one LVDS receiver, allowing LVTTL-compatible logic inputs and outputs to interface with LVDS signaling. The receiver input path includes a nominal 110 ohm line termination resistor, with receiver termination impedance specified from 88 ohm to 132 ohm under the stated test condition.
The device is intended for 3.3 V systems, with a recommended VCC range of 3.0 V minimum, 3.3 V nominal, and 3.6 V maximum. LVDS operation is specified at signaling rates of at least 250 Mbps and meets or exceeds ANSI/TIA/EIA-644A requirements. Receiver thresholds are specified at 100 mV maximum positive-going and -100 mV minimum negative-going differential input threshold.
Packaging is a 20-pin TSSOP (PW) with a 6.50 mm x 4.40 mm nominal body and 26-mil terminal pitch. The pinout assigns driver inputs to 1D, 2D, 3D, and 4D; differential driver outputs to Y/Z pairs; receiver inputs to 5A and 5B; receiver output to 5R; VCC to pins 4 and 8; and GND to pins 2, 6, and 10. Applications should stay within the -40 to 85 degC operating free-air temperature range and the recommended logic, differential input, common-mode, and supply limits.
