IDT821054APFG

The IDT821054APFG is an integrated device that features separate receiver and transmitter functions, with multiple I/Os, such as TDM, SPI, T1, E1, RGMII/GMII/MII, and an LVDS interface. This combination provides extremely high-performance signal conversion and advanced features. By using the technique of serial dimming with two serial communication interfaces, this device can transmit both analog and digital serial signals over the same physical device.

The IDT821054APFG is designed for the network terminal and the SMART transmission computer environment that processes serial I/O and DiSEqC 2.x signal data. Specifically, it is used for controlling Ethernet over coaxial interfaces and for converting DiSEqC 2.2 compliant serial data from the host device to RS-485/422. The device can also convert regulated voltages from Ethernet ports into SMPTE/DVB/DiSEqC signaling.

In terms of its application field, the IDT821054APFG is most suitable for use in cable, xDSL, DOCSIS, and optical networks. It can be used in the satellite, terrestrial, and cable networks that need a flexible and reliable way to bridge digital I/O devices with traditional broadcast protocols. The device also works great in digital video broadcast (DVB) networks where content is regularly upgraded or downgraded.

The working principle of the IDT821054APFG is to convert the serial digital data from the host into a serial bus protocol such as RS-485/422 for transmission on the medium. The device has a built-in DiSEqC 2.2 protocol engine that converts the data received from the host device into DiSEqC 2.2 compliant output. This allows the host microcontroller to control various satellite receivers, decoders, and E2E (end-to-end) transmission networks through a single interface. It also allow users to control diagnostic and monitoring networks in an easy and automated way.

The IDT821054APFG supports various Ethernet standards, including the 10/100/1000 BaseT and Standard Ethernet (IEEE802.3). It also provides ports for signaling, such as the direct coaxial cable, Wi-Fi, and RS-485/RS-422/RFC transport. The device supports a variety of different applications, such as Ethernet over Coax (EoC), Ethernet over VDSL (EoVDSL), and IP-over-DVB (IPoDVB).

The IDT821054APFG provides a low-power and cost-effective solution for a vast array of digital or analog video and audio broadcasting applications. Its adaptation to multiple networks and the standardized interfaces makes it reliable and very easy to use. The architecture of the device is designed to accommodate various materials and components, making it possible to use different combinations of chips in order to tune the device according to specific system requirements.
