Notes:

1. All tests guaranteed per test figure 6.

2. Guaranteed by device characterization.

3. Supplied as a design limit but not guaranteed or tested.

4. Delay time from transmit inhibit (1.5V) to transmit off (280mV).

CONDITION

Input ƒ = 1MHz 50% duty cycle:

direct-coupled RL = 35 ohms output at

10% through 90% points TXOUT,

TXOUT. Figure 3.

RXOUT to RXOUT; Figure 4.

TXIN to TXIN; Figure 4.

Direct-coupled stub; input ƒ = 1MHz,

3VPP (skew INPUT ± 150ns), rise/fall

time 200ns.

Input TXIN and TXIN should create

transmitter output zero crossings at

500ns, 1000ns, 1500ns, and 2000ns.

These zero crossings should not devi-

ate more than ± 25ns.

TXIN and TXIN toggling @ 1MHz;

TXIHB transitions from logic zero to

one.

TXIN and TXIN toggling @ 1MHz;

TXIHB transitions from logic one to

zero.
