    • A system in a package includes a printed circuit board and first and second SOCs. The printed circuit board is connected to a second circuit board mounted within a printer. The first SOC is mounted on the printed circuit board and includes a receiver and a transmitter. The receiver receives a first radio frequency signal from a low noise amplifier and generates a first baseband signal based on the first radio frequency signal. The transmitter transmits, based on a second baseband signal, a second radio frequency signal to a power amplifier. The second SOC is mounted on the printed circuit board and includes a baseband processing module and an imaging module. The baseband processing module processes the first baseband signal and the second baseband signal and generates a data signal based on the first baseband signal. The imaging module processes the data signal to implement physical printing.

    • There is disclosed a configuration for multiplexing the USB signals onto the IEEE 1284 signals thereby allowing a single connector on the device to support either protocol. Within the device, each protocol block is connected to transceiver to compensate for differences in driver/receiver characteristics for the protocol. The outputs of the transceivers are connected to a signal conditioner to allow proper selection of termination impedance. A controller senses whether a passive adapter is attached to the connector. When the passive adapter is not connected the controller selects the 1284 protocol and its associated transceiver and signal conditioning. If the passive adapter is connected, the controller selects the USB protocol and its associated transceiver and signal conditioning. The passive adapter connects pre-selected pins on the device's connector to a USB connector. There is also described an arrangement to allow the passive adapter and device to provide USB hub functions.
    • 公开了用于将USB信号复用到IEEE 1284信号上的配置,从而允许设备上的单个连接器支持任一协议。 在设备内,每个协议块连接到收发器以补偿协议的驱动器/接收机特性的差异。 收发器的输出连接到信号调节器,以允许正确选择终端阻抗。 控制器检测无源适配器是否连接到连接器。 当无源适配器未连接时,控制器选择1284协议及其相关收发器和信号调理。 如果连接了被动适配器,控制器将选择USB协议及其相关收发器和信号调理。 无源适配器将设备连接器上的预选引脚连接到USB连接器。 还描述了允许无源适配器和设备提供USB集线器功能的布置。
