Patent ID: 7349465

Claim:
A transceiver system for use in a telecommunication system, said transceiver system comprising: a transmission circuit including a differential transmitter input coupled via a transmitter input stage to a differential input of a transmission amplifier, said transmitter input stage including a trimmable resistor, one end of which is coupled to a positive transmit input, and the other end of which is coupled to a negative transmit input, said trimmable resistor providing a desired corner frequency to be set by adjusting the trimmable resistor; a receiver circuit including a differential receiver output coupled to a differential input of a receiver amplifier, dual negative feedback paths, a first differential input path having a first pair of capacitors, and a second differential input path having a second pair of capacitors, said first and second differential input paths providing first and second differential input signals from first and second filters respectively to the receiver amplifier; and a transmission line interface circuit coupled to a differential output of said transmission amplifier and to a differential input of said receiver amplifier.
