+

+192 kHz Digital Audio Receiver

+

+The CS8416 is a digital audio receiver that supports sample rates up to 192 kHz. It enables consumer and professional audio products to exchange S/PDIF and AES/EBU audio data. An 8:2 input multiplexer allows for up to eight channels of digital audio input data. The second output of the input multiplexer allows for a S/PDIF pass-through function for added system flexibility. It has an extremely low-jitter clock-recovery mechanism that yields a very clean recovered clock from the incoming audio stream. The device also allows for selectable signal routing to three general-purpose output pins. With its extremely low-jitter performance of 200 ps, the CS8416 is an industry-leading 192 kHz digital audio receiver. The CS8416 is ideal for consumer and professional applications such as audio/video receivers, multimedia speakers, digital mixing consoles, automotive audio systems and set-top boxes.

+## What is inside a SFP transceiver?

+

+Fiber optic transceivers are key components of the fiber optic transmission network. They are designed in small form-factor with some integrated optical sub-assemblies which can be suitable for the high-density network. There are many SFPs available in the market with different features and specifications(SFP & SFP+).

+

+Aren’t you aware of the major functions of these transceiver modules?

+

+- SFPs will transmit data and receive the data.

+- Transceivers provide the conversion of electrical signals to optical signals and vice versa.

+

+Inside the metal casing of a transceiver, there are several components and sub-assemblies that join together to form this.

+

+- Transmitter Optical Sub Assembly (TOSA)

+- Receiver Optical Sub Assembly (ROSA)

+- Bi-Directional Optical Sub Assembly (BOSA)
