11. Total Harmonic distortion with metering is specified with a metering signal of 2.2 Vrms at the two-wire output, and a transmit
signal of +3 dBm or receive signal of –4 dBm. The transmit or receive signals are single-frequency inputs, and the distortion
is measured as the highest in band harmonic at the two-wire or the four-wire output relative to the input signal.
12. Noise with metering is measured by applying a 2.2 Vrms metering signal (measured at the two-wire output) and measuring
the psophometric noise at the two-wire outputs over a 200 ms time interval.
Note:
* A logic Low on E0 disables DET output into the Open Collector state.

User-Programmable Components
ZT is connected between the VTX and RSN pins. The fuse
resistors are RF, and Z2WIN is the desired two-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.
ZRX is connected from VRX to RSN. ZT is defined above. This
equation sets the receive gain to 0 dB when the SLIC
terminates with an impedance equal to Z2WIN.
RDC1, RDC2, and CDC form the network connected to the RDC
pin. RDC1 and RDC2 are approximately equal.
RD and CD form the network connected from RD to –5 V and IT
is the threshold current between on-hook and off-hook.
ZM is connected from VMG (metering source) to the RSN pin,
VM2W is the desired magnitude of the metering signal at the
2-wire output (usually 2.2 Vrms) and K1 ( ) is defined below.
