Detailed Description

SBS 4400-VF10 Tunable Bit Synchrozier Interface Library.

The SBS 4400-VF10 bit sync board provides bit edge detection and clock recovery of the GLAST BFEM telemetry bit stream. The input is the bi-phase signal from the NSBF telemetry receiver. The output is a NRZ and clock signal pair which is suitable for input to the ISOMAX telemetry frame sync board.
