Miscellaneous
IDT82P2816
Rx: Fully Internal Impedance Matching mode. In this mode, there is no external resistor required. The R_TERM[2:0] bits (b2~0, RCF0,...)
setting is as follows: ‘000’ for T1 100 Ω twisted pair cable, ‘001’ for J1 110 Ω twisted pair cable, ‘010’ for E1 120 Ω twisted pair cable and
‘011’ for E1 75 Ω coaxial cable.
Tx: Internal Impedance Matching mode. The T_TERM[2:0] bits (b2~0, TCF0,...) setting is as follows: ‘000’ for T1 100 Ω twisted pair
cable, ‘001’ for J1 110 Ω twisted pair cable, ‘010’ for E1 120 Ω twisted pair cable and ‘011’ for E1 75 Ω coaxial cable.
