The transmit chain has a 14 Bit DAC, a third-order Chebyshev reconstruction filter and a programmable attenuator (-12 to 0dB) capable of driving a 220Ω differential load.
The receiver chain has a high impedance input stage, programmable gain stage (0 to 24dB), additional programmable gain (-9 to 18dB) and a third-order Chebyshev anti-aliasing filter for driving an off-chip A/D.
Laser trimmable thin-film resistors are used to set the filter cutoff frequency and DAC linearity.
The transmit and receive signal chains are specified at 65dB MTPR.
