Physical And Electrical Specifications
IDT82P2821
Note:
1. Test conditions: VDDx (maximum) at 85 °C operating temperature (ambient).
2. The transmitter is in Internal Impedance Matching mode and the receiver is in Fully Internal Impedance Matching mode. That is, the R120IN bit (b4, RCF0,...) is set to ‘1’. And the
T_TERM[2:0] bits (b2~0, TCF0,...) and R_TERM[2:0] bits (b2~0, RCF0,...) are set according to different cable conditions.
3. The transmitter is in Internal Impedance Matching mode and the receiver is in Partially Internal Impedance Matching mode. That is, the R120IN bit (b4, RCF0,...) is set to ‘0’. And the
T_TERM[2:0] bits (b2~0, TCF0,...) and R_TERM[2:0] bits (b2~0, RCF0,...) are set according to different cable conditions.
4. For E1 mode, both the transmitter and the receiver are in External Impedance Matching mode. That is, the T_TERM[2:0] bits (b2~0, TCF0,...) are set to ‘111’ and the R_TERM[2:0]
bits (b2~0, RCF0,...) are set to ‘1xx’. For T1/J1 mode, as the transmitter External Impedance Matching mode is not supported, the transmitter is in Internal Impedance Matching mode
and the receiver is in Internal Impedance Matching mode. That is, the T_TERM[2:0] bits (b2~0, TCF0,...) are set according to different cable conditions and the R_TERM[2:0] bits
(b2~0, RCF0,...) are set to ‘1xx’.
