ODT Characteristics
fication requirements; however, they can be used as design guidelines to indicate what
RTT is targeted to provide:
• RTT 120Ω is made up of RTT120(PD240) and RTT120(PU240).
• RTT 60Ω is made up of RTT60(PD120) and RTT60(PU120).
• RTT 40Ω is made up of RTT40(PD80) and RTT40(PU80).
