Digital I/O Connections Logic Supply. Connect a +1.65V to +3.6V supply to V
GND with a 0.1µF ceramic capacitor.
Speed-Selector Input. Connect SPD to GND to select the low-speed data rate (1.5Mbps).
Connect SPD to V
Differential-Receiver Output. RCV responds to the differential input on D+ and D- (Tables 3 and
4). RCV asserts low if SUS = V
Receiver Output/Driver Input. VP functions as a receiver output when OE = V
when receiving. VP functions as a driver input when OE = GND.
Receiver Output/Driver Input. VM functions as a receiver output when OE = V
when receiving. VM functions as a driver input when OE = GND.
No Connection. Not internally connected.
Ground
Suspend Input. Drive SUS low for normal operation. Drive SUS high to put the MAX3450E/
MAX3451E/MAX3452E into suspend mode. RCV asserts low in suspend mode. VP and VM
remain active in suspend mode.
Output Enable. Drive OE to GND to enable the transmitter outputs. Drive OE to V
transmitter outputs. OE also controls the I/O direction of VP and VM (Tables 3 and 4).
