The receiver outputs can be switched to either or both drivers through the multiplexer control signals S0 and S1. This allows the flexibility to perform splitter or signal routing functions with a single device. • Designed for Signaling Rates up to 650 Mbit/s (325 MHz) • Operates from a 3.3V Supply: –40°C to +85°C • Low Voltage Differential Signaling with Output Voltages of ±350mV into: - 100 Ohm load (PI90LV022) - 50 Ohm load Bus LVDS Signaling (PI90LVB022) The LVDS standard provides a minimum differential output voltage magnitude of 247mV into a 100 Ohm load and receipt of 100mV DC signals with up to 1V of ground potential difference between a transmitter and receiver. The PI90LVB022 doubles the output drive current to achieve Bus LVDS signaling levels with a 50 Ohm load. A doubly terminated Bus LVDS line enables multi-point configurations. Switching between channels does not create false transitions on the outputs. • Accepts ±350mV differential inputs • Wide common mode input voltage range: 0.2V to 2.7V • Output drivers are high impedance when disabled or when VCC ≤ 1.5V • Inputs are open, short, and terminated fail safe The intended application of these devices and signaling technique is for both point-to-point base-band (PI90LV022) and multipoint (PI90LVB022) data transmissions over controlled impedance media. • Propagation Delay Time: 3.5ns • ESD protection is 10kV on bus pins • Bus Pins are High Impedance when disabled or with VCC less than 1.5V • TTL Inputs are 5V I/O Tolerant • Power Dissipation at 400Mbit/s less than 150mW • Industrial temperature rating • Packaging (Pb-free & Green available): - 16-pin TSSOP (L) Block Diagram Pin Configuration 1DE 1B 1 16 VCC 15 VCC 1A + 1Y 1A 2 1B – 1Z S0 3 1DE 2A + 2Y 2B – 2Z 2DE 14 16-Pin 4 L 13 1Y 1Z S1 5 12 2DE 2A 6 11 2Z 2B 7 10 2Y GND 8 9 GND S0 S1 08-0295 1 PS8488C 10/28/09 PI90LV022, PI90LVB022 LVDS Mux / Repeater 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 Table 1.
