User-Programmable Components

Where ZT is connected between the VTX and RSN pins. The

fuse resistors are RF, and Z2WIN is the desired 2-wire AC input

impedance. When computing ZT, the internal current amplifier

pole and any external stray capacitance between VTX and

RSN must be taken into account.

Where ZRX is connected from VRX to the RSN pin, ZT is

defined above, and G42L is the desired receive gain.

Where RDC1, RDC2, and CDC form the network connected to

the RDC pin. RDC1 and RDC2 are approximately equal.

Where RD and CD form the network connected from RD to –5 V

and IT is the threshold current between on hook and off hook.
