1. This table contains propagation delays from the TP ports to the IRB for normal repeater operation. All values in this table are
output timings.
2. Typical values are at 25
°
C and are for design aid only; not guaranteed and not subject to production testing.
3. There is a delay of approximately 13 to 16 bit times between the assertion of IR10ENA and the assertion of IR10CLK and
IR10DAT. This delay does not affect repeater operation because downstream devices begin generating preamble as soon as
IR10ENA is asserted.
4. Bit Time (BT) is the duration of one bit as transferred to/from the MAC and is the reciprocal of bit rate. BT for 10BASE-T =
10
s or 100 ns.
