The MAX9248/MAX9250 digital video serial-to-parallel converters deserialize a total of 27 bits during data and control phases. In the data phase, the LVDS serial input is converted to 18 bits of parallel video data and in the control phase, the input is converted to 9 bits of parallel control data. The separate video and control phases take advantage of video timing to reduce the serial-data rate. The MAX9248/MAX9250 pair with the MAX9247 serializer to form a complete digital video transmission system. For operating frequencies less than 35MHz, the MAX9248/MAX9250 can also pair with the MAX9217 serializer.The MAX9248 features spread-spectrum capability, allowing output data and clock to spread over a specified frequency range to reduce EMI. The data and clock outputs are programmable for a spectrum spread of ±4% or ±2%. The MAX9250 features output enable input control to allow data busing.Proprietary data decoding reduces EMI and provides DC balance. The DC balance allows AC-coupling, providing isolation between the transmitting and receiving ends of the interface. The MAX9248/MAX9250 feature a selectable rising or falling output latch edge. ESD tolerance is specified for ISO 10605 with ±10kV Contact Discharge and ±30kV Air-Gap Discharge.The MAX9248/MAX9250 operate from a +3.3V ±10% core supply and feature a separate output supply for interfacing to 1.8V to 3.3V logic-level inputs.

The LTC4309 hot swappable 2-wire bus buffer allows I/O card insertion into a live backplane without corruption of the data and clock busses. The LTC4309 provides bidirectional buffering, keeping the backplane and card capacitances isolated. Low offset and high VOL tolerance allows cascading of multiple devices on the clock and data busses. If SDAOUT or SCLOUT are low for 30ms, FAULT will pull low indicating a stuck bus low condition. If DISCEN is tied high, the LTC4309 will automatically break the bus connection and generate up to 16 clock pulses and a stop bit in an attempt to free the bus. A connection will resume if the stuck bus is cleared. If DISCEN is connected to GND, the busses will remain connected with no clock or stop bit generation. ACC input enables rise-time accelerators for high capacitively loaded busses.During insertion, the SDA and SCL lines are precharged to 1V to minimize bus disturbances. When driven high, the ENABLE input allows the LTC4309 to connect after a stop bit or bus idle. Driving ENABLE low breaks the connection between SDAIN and SDAOUT, SCLIN and SCLOUT. READY is an open drain output which indicates that the backplane and card sides are connected.Applications Live Board Insertion Servers Capacitance Buffer/Bus Extender RAID Systems ATCA

Using an on-chip bridge-tied load mono headphone amplifier, the MAX9860 can output 30mW into a 32Ω earpiece while operating from a single 1.8V power supply. Very low power consumption makes it an ideal choice for battery-powered applications.The MAX9860's flexible clocking circuitry utilizes common system clock frequencies ranging from 10MHz to 60MHz, eliminating the need for an external PLL and multiple crystal oscillators. Both the ADC and DAC support sample rates of 8kHz to 48kHz in either synchronous or asynchronous operation. Both master and slave timing modes are supported.Two differential microphone inputs are available with a user-programmable preamplifier and programmable gain amplifier. Automatic gain control with selectable attack/release times and signal threshold allows maximum dynamic range. A noise gate with selectable threshold provides a means to quiet the channel when no signal is present. Both the DAC and ADC digital filters provide full attenuation for out-of-band signals as well as a 5th order GSM-compliant digital highpass filter. A digital side tone mixer provides loopback of the microphones/ADC signal to the DAC/headphone output.Serial DAC and ADC data is transferred over a flexible digital I²S-compatible interface that also supports TDM mode. Mode settings, volume control, and shutdown are programmed through a 2-wire, I²C-compatible interface.The MAX9860 is fully specified over the -40°C to +85°C extended temperature range and is available in a low-profile, 4mm x 4mm, 24-pin thin QFN package.Request S/W DriversApplicationsAudio AccessoriesAudio HeadsetsMobile PhonesPortable Navigation DeviceSmart PhonesVoIP Phones
