S1D13503F00A1

The S1D13503F00A1 is one member of the S1D13503 series.The transmit channel consists of a digital-to-analog converter and switched-capacitor pulse forming network followed by a differ- ential line driver. The pulse forming network receives symbol data and generates a standard 2B1Q output waveform. The differential line driver uses a composite output stage combining class B operation (for high efficiency driving large signals) with class AB operation (to minimize crossover distortion).

Both the S1D13503F00A1 backplane bias and the CCFL supply can be shut down independently. When both sections are shut down, supply current drops to 25µA. The LCD contrast and CCFL brightness can be adjusted by clocking sep- arate digital inputs or using external potentiometers. LCD contrast and backlight brightness settings are pre- served in their respective counters while in shutdown. On power-up, the LCD contrast counter and CCFL brightness counter are set to one-half scale. The ICs are powered from a regulated 5V supply. The magnetics are connected directly to the battery, for maximum power efficiency. The CCFL driver uses a Royer-type resonant architec- ture. It can provide from 100mW to 6W of power to one or two tubes. The MAX753 provides a negative LCD bias voltage; the MAX754 provides a positive LCD bias voltage.
