PRODUCTION DATA
When a PCLK is not applied to the DS90UB913A, the serializer will establish the FPD-III link using an internal oscillator. During normal operation (not BIST) the frequency of the internal oscillator can be adjusted from DS90UB913A register 0x14[2:1] according to Table 7-3. In BIST mode, the internal oscillator frequency should only be adjusted from the DS90UB914A. The BIST frequency can be set by either pin strapping (Table 7-4) or register (Table 7-5). In BIST DS90UB913A register 0x14[2:1] is automatically loaded from the DS90UB914A through the bi-directional control channel.
