Working Principle

THCV217-B is a versatile single-channel serializer/deserializer (SERDES) device which interfaces a low voltage logic interface to a one-channel high voltage interface. It enables data transmission from the low voltage interface to the high voltage interface (serialization) and data reception from the high voltage interface to the low voltage interface (deserialization).

The SERDES consists of three main components; an On-chip phase locked loop (PLL), a transmit/receive core and control logic circuits. The PLL is used to provide the frequency synthesis used to clock the data streams from the low voltage logic interface. The transceiver core is responsible for serializing/deserializing the data to/from the high voltage interface using double data rate (DDR) coding. The control logic circuits include a presetable counter which is used to control the serialization/deserialization process.

The THCV217-B SERDES enables audio data transmission over various link such as IEEE 1394a and SPDIF using a single device with no external components, providing high performance and reliability.
