    Abstract: In order to compensate for rate mismatches between near end (receiving) and far end (transmitting) devices, intelligent jitter buffer management is implemented by apparatus comprising: a data interface for receiving frames from a data network; a jitter buffer for temporarily storing said frames; a detector for detecting frames which satisfy a criteria; and a buffer manager for controlling the frames stored in said jitter buffer based on the condition of said buffer and on frames which satisfy said criteria. The criteria can include silence frames or frames received with errors. The condition can include a high water mark (high threshold), and a low water mark (low threshold). If the far end transmitter transmits at a faster rate than the near end receiver, the jitter buffer will eventually become full beyond the high water mark, in which case frame(s) which satisfy the criteria will be deleted. If the far end transmitter transmits at a slower rate than the near end receiver, the jitter buffer will eventually become depleted below the low water mark, in which case silence frame(s) will be inserted after received silence frames.

    Abstract: A bias network for providing the ECL reference voltages V.sub.REF1 and V.sub.REF2. Bipolar npn transistors are arranged to receive the collector terminal potentials of the emitter-coupled pair of the bias network. The npn transistors form the input devices of a differential amplifier that includes a pair of FETs arranged as a current mirror. One of each of such FETs is in series with each of the input transistors. The differential amplifier regulates the potential at an internal node of the bias network to thereby maintain the operating point of the network so that the potentials of the collector terminals are equal. As a result the bias network is rendered substantially insensitive to both temperature and supply voltage variations.

    Abstract: An improved tri-state output buffer of the type that includes an output stage comprising a pair of bipolar transistors in a totem-pole configuration. A CMOS predriver arrangement includes a circuit configuration for selectively adjusting the resistance between the base and the emitter of the source-follower output transistor. The predriver protects the source-follower from harmful bias effects by selectively adjusting the resistance in the emitter-to-base path of the source-follower.

    Abstract: A broad-band cavity-tuned transistor oscillator includes a field effect device having capacitive feedback from source to drain and having a gate capacitively coupled to a cavity for producing an output signal that is frequency selectable according to cavity resonance, which resonance is determined by translation position of a mechanical tuning plunger coupled to the cavity and the degree of capacitive feedback.
