MT9075BP1 Zarlink, MT9075BP1 Datasheet - Page 10

• Manufacturer Part Number: MT9075BP1
• Description: PB FREE E1 SINGLE CHIP TRANSCEIVER
• Manufacturer: Zarlink

The template for the transmitted pulse, as specified in G703, is shown in Figure 5. The nominal peak voltage of a
mark is 3 volts for 120 Ω twisted pair applications and 2.37 volts for 75 Ω coax applications. The ratio of the
amplitude of the transmit pulses generated by TTP and TRING is between 0.95 and 1.05.
