Manufacturer:TI Description:The TLC0820ACFNG3/TLC0820ACFNG3/TLC0820ACFNG3 low-power, low-dis- tortion, class-G, high-current asymmetric digital sub- scriber line (ADSL) drivers offer Rail-to-Rail® output and are ideal for ADSL in central-office applications. Operating from 5V and 2.5V supplies, the drivers incorporate two high-speed current-feedback preampli- fiers driving two fixed-gain class-G buffers. The buffers can deliver 20.4dBm average line power with a signal crest factor of 5.3, and are designed to be directly DC or AC bridged across a 1:2.5 transformer. The TLC0820ACFNG3/TLC0820ACFNG3/TLC0820ACFNG3 employ an active line termination scheme for incoming signals that eliminates the need for back-match resistors, reducing line-card power consumption at full rate to less than half of that required by conventional class-AB line-driver circuits. The TLC0820ACFNG3 includes a hybrid network and two low- noise, fixed-gain-of-4.6V/V receive amplifiers. The part is designed to recover the receive signal to the same level as that of a conventional line interface circuit that incor- porates a 1:2 transformer and standard back-matched hybrid, without degrading signal-to-noise ratio (SNR) or line-impedance sensitivity. The TLC0820ACFNG3 provides only the preamplifiers and buffers without the hybrid or receivers. The TLC0820ACFNG3 provides preamplifiers, buffers, and uncommitted receive amplifiers. All devices have a low-output-impedance shutdown function for saving power when not transmitting. At full-rate 20.4dBm discrete multitone data transmission (DMT), the total dynamic power dissipation is only 680mW (TLC0820ACFNG3/TLC0820ACFNG3) or 655mW (TLC0820ACFNG3). The TLC0820ACFNG3/TLC0820ACFNG3 are available in a 20-pin TSSOP package and the TLC0820ACFNG3 is available in 28-pin TSSOP and 32-pin QFN packages. All devices operate over the extended -40C to +85C temperature range. |
