The STVMOCA device, in conjunction with the AFE transceiver, connects ST back-end devices to the home MoCA network as defined by the MoCA standard (specification v1.1). The STVMOCA chip is mainly associated with the back-end devices of the STx71xx family, such as STi7105, and the STiHXXX families.
The STVMOCA chip contains MAC and PHY processing and a high-speed SERDES interface to the analog front-end (AFE) device.
The IC may be interfaced to the host processor via the GMII port.
