The TF90LVDS048 and TF90LVDT048 are 400 Mbps Quad LVDS (low voltage differential signaling) Line Receivers optimized for high-speed, low power, low noise transmission over controlled impedance (approximately 100 ohms) transmission media (e.g. cables, printed circuit board traces, backplanes).
The TF90LVDS048 and TF90LVDT048 input receivers support wide input voltage range of -7V to 12V for exceptional noise immunity.
The TF90LVDS048 and TF90LVDT048 accept four LVDS signals and translate them to four LVCMOS signals. The outputs can be disabled and put in a high-impedance state via two enable pins, OE and OE*. The flow-through pinout simplifies PCB layout and minimizes crosstalk by isolating the LVDS inputs from the LVCMOS / LVTTL outputs.
The TF90LVDT048 features on-chip 100 ohm input termination resistors that minimize input return loss, component count and board space. The TF90LVDS048 differential inputs are without input termination resistors and are suitable for applications requiring custom termination schemes.
