The receiver portion of the TLK1521 accepts 20-bit framed differential serial data. The interpolator and clock recovery circuit locks to the data stream and extracts the bit rate clock. This recovered clock is used to retime the input data stream. The serial data is then aligned to the 20-bit word boundary by finding the start/stop bits and the 18-bit data is output on a 18-bit wide parallel bus synchronized to the extracted receive clock.

(5) When designing your equipment, comply with the guaranteed values, in particular those of maxi- mum rating, the range of operating power supply voltage and heat radiation characteristics. Other- wise, we will not be liable for any defect which may arise later in your equipment. Even when the products are used within the guaranteed values, redundant design is recommended, so that such equipment may not violate relevant laws or regulations because of the function of our products.
