Notes:
1. Only applicable when TXC has been configured as an INPUT.
2. Only applicable when TXC has been configured as an OUTPUT.
3. MIN value not tested.
4. Parameter calculated from other parameters.
5. Clock period must correlate to data rate as specified n DR bits of TCR30. Note that data rate s a function of DR and T
CLKIN
and
CLKGT20 bit of MIR9.
6. The values for these parameters are given for the case with CLKP = 0 (TCR2[4:0]). For nonzero values of CLKP, use the
following formulas:
If CLKGT20 = 0 (MIR9[7]),
t
RXDS
min = 110–CLKP X T
CLKIN
t
RXDH
min = 10+CLKP X T
CLKIN
If CLKGT20 = 1 (MIR9[7]),
t
RXDS
min = 110–CLKP X T
CLKIN
X2
t
RXDH
min = 10+CLKP X T
CLKIN
X2
7. Values given are for data rate of 1Mb/s. For other data rates,
t
TXC
is 1/DR, where DR = data rate in Hertz,
t
CLTX
is 60% of T
TXC
minus T
TXHL
,
t
CHTX
is 40% of T
TXC
minus T
TXHL
,
t
TXCO
is 1/DR, where DR = data rate in Hertz,
t
CLTXO
is 60% of T
TXCO
minus T
TXHLO
,
t
CHTXO
is 40% of T
TXCO
minus T
TXHLO
,
t
TXHLO
is 15 ns, regardless of DR value,
t
TXLHO
is 15 ns, regardless of DR value.
8. Parameter not included in the production test.
