Description
The DS99R101/DS99R102 Chipset translates a 24-bit parallel bus into a fully transparent data/control LVDS serial stream with
embedded clock information. This single serial stream simplifies transferring a 24-bit bus over PCB traces and cable by eliminating
the skew problems between parallel data and clock paths. It saves system cost by narrowing data paths that in turn reduce
PCB layers, cable width, and connector size and pins.
The DS99R101/DS99R102 incorporates LVDS signaling on the high-speed I/O. LVDS provides a low power and low noise environment
for reliably transferring data over a serial transmission path. By optimizing the serializer output edge rate for the operating
frequency range EMI is further reduced.
Internal DC balanced encoding/decoding is used to support AC-Coupled interconnects.
Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
