Pin
Recommended Connection of Unused Pins
Each input pin at level
other than P-ECL
Connect to ground (parallel input pin in serial mode)
RPD0 through RPD7, RPC, TFC
(Multi-PHY pins in single PHY mode)
TADD0 to TADD4, RADD0 through RADD4
(others)
TFSS (essential)
Each input pin at P-ECL
level
Pull up True(+) pins (TFKT, RCIT, RDIT) to 3.3 V. Connect
Complement(
) pins (TFKC, RCIC, RDIC) to ground.
Output pin
Leave open.
(Parallel input pins in serial mode)
TPD0 to TPD7
TPC
(others)
TxFP, RxFP, TCL, RCL
Output pin at P-ECL level
Leave open.
TDOT, TDOC, TCOT, TCOC
AIN1
Leave Open.
Because noise on this pin affects the characteristics of the
internal PLL, do not wire a clock line in the vicinity.
