MAX9157 Quad Bus LVDS Transceiver - Maxim

Quad Bus LVDS TransceiverMAX9157AC ELECTRICAL CHARACTERISTICS(V CC = 3.0V to 3.6V, R L = 27Ω ±1%, differential input voltage |V ID | = 0.2V to V CC , input frequency to LVDS inputs = 85MHz, input frequencyto LVCMOS/LVTTL inputs = 100MHz, LVCMOS/LVTTL inputs = 0 to 3V with 2ns (10% to 90%) transition times. Differential inputvoltage transition time = 1ns (20% to 80%). Input common-mode voltage V CM = 1.2V to 1.8V, DE_ = high, RE_ = low, T A = -40°C to+85°C, unless otherwise noted. Typical values are at V CC = 3.3V, |V ID | = 0.2V, V CM = 1.2V, and T A = +25°C.)
