SWITCHING CHARACTERISTICS (continued)
*Min = 4.5 V, Max = 5.5 V, T
OSC
= 50 ns; in production test, all differential input test conditions are done single-ended,
non-V
IRD
levels are forces on DUT for waveform swing (levels chosen are due to tester limitations) and a distortion-free
preamble is applied to Receive
±
inputs.
Notes:
1. Tested but to values in excess of limits. Test accuracy not sufficient to allow screening guardbands.
2. Correlated to other tested parameter: I
OD
OFF = V

OFF/R
L
.
3. Not tested.
4. Test done by monitoring output functionally.
5. Receive, Collision and Transmit functions are inactive: X1 driven by 20 MHz.
6. Not more than one output should be shorted at a time. Duration of the short circuit test should not exceed one second.
7. TCLK changes state on X1 rising edge, but initial state of TCLK is not defined. When TENA is High, TX data is
Manchester encoded on the falling edge of X1 after the rising edge of TCLK.
8. Assumes 50 pF capacitance loading on RCLK and RX.
9. Test is done only for last BIT = 1, which is worst case.
10. Test done from 0.8 V of falling to 2.0 V of rising edge.
11. Test correlated to T
TCH
.
12. Measured from 50% point of X1 driving the input in production test.
No.
