The TDA1997BEL/C1E is an integrated circuit that is part of the TDA1997 family of low power level 1 (LP1) transceivers. This device has been developed specifically to enable the transmission and reception of HDTV signals up to 10Mbps. It has been designed to minimize power consumption while optimizing performance.

The TDA1997BEL/C1E belongs to Interface - Telecom, and is used in HDTV and digital video transmission applications. It provides differential input and output stages, with a wide power supply range of 3.0V to 6.0V, and can operate at temperatures as low as -20°C. The device also supports I/O supply voltage levels of 1.8V, 2.5V, and 3.3V, enabling the implementation of LVDS regulation.

The TDA1997BEL/C1E is designed to transmit and receive up to 8 data streams. It is capable of data rates up to 10Mbps for each data stream, and supports a wide variety of data formats, including ITU G.709, 16QAM, 64QAM, and 256QAM. The device also has adjustable equalization circuits to optimize performance in RGB and YCbCr data formats.

The TDA1997BEL/C1E supports low-power operation, featuring programmable power management modes to reduce current consumption. It also features programmable output level control and slew rate limiting to reduce EMI radiation. The device also supports both LVDS and TTL data interfaces.

In terms of its working principle, the TDA1997BEL/C1E consists of a differential input stage, an output stage, and a digital interface with control registers. The differential inputs are used to receive the data being transmitted, while the output stage drives the data lines. The control registers provide the logic to control the output drivers. The device also has adjustable equalization circuits that provide optimized performance for different video formats.

The TDA1997BEL/C1E also features a burst mode operation, allowing the device to remain in its low-power state until a burst of data is received. The device automatically enters the burst mode after each transmission is completed. The device is also capable of data scrambling, in order to reduce EMI radiation and improve data integrity.

Overall, the TDA1997BEL/C1E is a versatile and power efficient LP1 transceiver. It is a feature-rich device designed for HDTV and digital video transmission applications. The device offers low power consumption, adjustable equalization for improved performance, low-power mode for reduced power consumption, and data scrambling for improved EMI suppression.
