FlexRay transceiver

[1]

Rise and fall time (10 % to 90 %) of tr(TXD) and tf(TXD) = 5 ns  1ns.

[2]

Rise and fall time (10 % to 90 %) of tr(TRXD) and tf(TRXD) = 5 ns  1ns.

[3]

The worst case asymmetry from one branch to another is the sum of the delay difference from TRXD0 and TRXD1 to DATA_0 and

DATA_1 plus the delay difference from DATA_0 and DATA_1 to TRXD0 and TRXD1.

Dynamic characteristics …continued

All parameters are guaranteed for VBAT = 6.5 V to 60 V; VCC = 4.75 V to 5.25 V; VBUF = 4.75 V to 5.25 V; VIO = 2.2 V to 5.25 V;

Tvj = 40 C to +150 C; Rbus = 45 ; RTRXD = 200  unless otherwise specified. All voltages are defined with respect to

ground; positive currents flow into the IC.
