The device is designed to support data rates in excess of 500 Mbps (250 MHz) using Low Voltage Differential Signaling (LVDS) technology. The devices accept low-voltage (350 mV typical) differential input signals and translates them to 3V CMOS output levels. The receiver supports a 3-state function, which may be used to multiplex outputs, and also supports open, shorted and terminated (100-ohms) input fail- safe. The receiver output will be HIGH for all fail-safe conditions. PI90LVT048A features integrated parallel termination resistors (nominally 110-ohms) that eliminate the requirement for four dis- crete termination resistors and reduce stud length. PI90LV048A inputs are high impedance and require an external termination resistor when used in a point-to-point connection. The devices have a flow-through pinout for easy PCB layout. The EN and EN inputs are ANDed together and control the 3-state outputs. The enables are common to all four receivers. The PI90LV048A and companion LVDS line driver (eg. PI90LV047A) provide a new alternative to high-power PECL/ECL devices for high-speed point-to-point interface applications. 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 PI90LV048A/PI90LVT048A 3V LVDS Quad Flow-Through Differential Line Receivers s e l b a n Es t u p n Is t u p t u O N EN ER + N I R – – N I R T U O Hn e p O r o L V D I ≥ V 1 . 0H V D I ≤ V 1 . 0 –L d e t a n i m r e t r o T R O H S / N E P O e f a s -l i a f ll u FH s t u p n i E L B A N E f o s n o it a n i b m o c r e h t o ll AX Z TruthTable PinConfiguration RIN1+ EN EN ROUT1 ROUT2 ROUT3 ROUT4 RIN1– RIN2+ RIN2– RIN3+ RIN3– RIN4+ RIN4– R1 R2 R3 R4 100 4 Places PI90LVT048A Only 08-0295 |
