A predictive time base generator having predictive synchronizer and replica delay element coupled with the synchronizer feedback delay loop. The predictive time base generator receives a clock signal delayed by a predetermined clock delay and produces a predictive time signal advanced in time by an amount represented by the replica delay element. The replica delay element can replicate one or both of a predetermined clock delay and a predetermined data delay, substantially nullifying the respective delays in critical signal paths of a device. The replica delay element can include replicas of structure(s) found in an incoming clock path and an outgoing data path, such elements including, for example, voltage level shifters, buffers or data latches, multiplexers, wire element models, and the like. A predictive computer bus interface adapter which incorporates the aforementioned predictive time base generator also is provided. Such a predictive interface adapter can be adapted to be observant of stringent bus protocol timing budgets imposed under the PCI and PCI-X local bus protocol, and to be robust relative to variations in design and fabrication processes, and environmental operating conditions.

To provide two clock signals (CLK1, CLK2) of slightly different frequencies (f1, f2) with defined time or phase delay, the first clock signal (CLK1) is generated at the first clock frequency (f1), the first clock frequency (f1) is divided by a first integer (K1) to produce a first auxiliary signal (CLK11), the second clock signal (CLK2) is divided by a second integer (K2) to produce a second auxiliary signal (CLK21), an error signal (ERR) is generated by individually weighting and comparing the cycle durations or phasing of the first and second auxiliary signals (CLK11, CLK21), and said second clock signal (CLK2) is generated by means of a voltage-controlled oscillator (17) controlled by said error signal (ERR).

Systems, apparatus, methods and computer program products are provided for causing a dataframe to be emitted at an air interface of an antenna. A memory stores a transmission to antenna delay value (TAD). An offset calculator calculates an offset value based on an epoch of a global timebase generator and the transmission to antenna delay value (TAD). An interface controller in communication with the offset calculator communicates a segment synchronization signal and a field synchronization signal based on the offset value.
