The MAX9205/MAX9207 serializers transform 10-bit-wide parallel LVCMOS/LVTTL data into a serial high-speed bus low-voltage differential signaling (LVDS) data stream. The serializers typically pair with deserializers like the MAX9206/MAX9208, which receive the serial output and transform it back to 10-bit-wide parallel data.The MAX9205/MAX9207 transmit serial data at speeds up to 400Mbps and 660Mbps, respectively, over PCB traces or twisted-pair cables. Since the clock is recovered from the serial data stream, clock-to-data and data-to-data skew that would be present with a parallel bus are eliminated.The serializers require no external components and few control signals. The input data strobe edge is selected by TCLK_R/F. Active-low PWRDN is used to save power when the devices are not in use. Upon power-up, a synchronization mode is activated, which is controlled by two SYNC inputs, SYNC1 and SYNC2.The MAX9205 can lock to a 16MHz to 40MHz system clock, while the MAX9207 can lock to a 40MHz to 66MHz system clock. The serializer output is held in high impedance until the device is fully locked to the local system clock, or when the device is in power-down mode.Both the devices operate from a single +3.3V supply, are specified for operation from -40°C to +85°C, and are available in 28-pin SSOP packages.ApplicationsAdd/Drop MultiplexersBackplane and Interconnect ApplicationsCell Phone Base Stations Digital Cross-ConnectsDSLAMNetwork Routers and Switches

The SSM2135 dual audio operational amplifier permits excel-lent performance in portable or low power audio systems, with an operating supply range of 4 V to 36 V or ±2 V to ±18 V. The unity-gain stable device has very low voltage noise of 5.2 nV/√Hz, and total harmonic distortion plus noise below 0.01% over normal signal levels and loads. Such characteristics are enhanced by wide output swing and load drive capability. A unique output stage1 permits output swing approaching the rail under moderate load conditions. Under severe loading, the SSM2135 still maintains a wide output swing with ultralow distortion. Particularly well suited for computer audio systems and portable digital audio units, the SSM2135 can perform preamplification, headphone and speaker driving, and balanced line driving and receiving. Additionally, the device is ideal for input signal conditioning in single-supply, Σ-Δ, analog-to-digital converter subsystems such as the AD1877. The SSM2135 makes an ideal single-supply stereo output amplifier for audio digital-to-analog converters (DACs) because of its low noise and distortion.The SSM2135 is available in an 8-lead plastic SOIC package and is guaranteed for operation over the extended industrial temperature range of −40°C to +85°C.

The HMC311SC70(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT DC to 8 GHz amplifier. Packaged in an industry standard SC70, the amplifier can be used as either a cascadable 50 Ohm gain stage or to drive the LO port of HMC mixers with up to +15 dBm output power. The HMC311SC70(E) offers 15 dB of gain and an output IP3 of +30 dBm while requiring only 54 mA from a +5V supply. The Darlington topology results in reduced sensitivity to normal process variations, and yields excellent gain stability over temperature while requiring a minimal number of external bias components.Applications Cellular / PCS / 3G WiBro / WiMAX / 4G Fixed Wireless & WLAN CATV, Cable Modem & DBS Microwave Radio & Test Equipment

The HMC1034LP6GE is a low-noise, wide-band clock generator IC with a fractional-N Phase Locked Loop (PLL) that features an integrated Voltage Controlled Oscillator (VCO).
