Intersil HC6094
The HC6094 performs the Analog processing for the ADSL chip set. 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.| Part No. | HC6094 |
