45 / 68 page  October 2004 45 M9999-101204 MIC3000 Micrel Laser Diode Bias Current MSB (ILDh) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read-only read-only read-only read-only read-only read-only read-only read-only Default Value 0000 0000b = 00h (0mA)(3) Serial Address A2h = 1010001b Byte Address 100 = 64h This register is to be used in conjunction with ILDl to yield a sixteen-bit value. The values in ILDh:ILDl are in an un- signed binary format. The value in this register is uncalibrated. The host should process the results using the scale factor and offset provided. See the External Calibration sections. Laser Diode Bias Current LSB (ILDl) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read-only read-only read-only read-only read-only read-only read-only read-only Default Value 0000 0000b = 00h (0mA) Serial Address A2h = 1010001b Byte Address 101 = 65h Each LSB represents 2 µA. This register is to be used in conjunction with ILDh to yield a sixteen-bit value. The values in ILDh:ILDl are in an unsigned binary format. The value in this register is uncalibrated. The host should process the results using the scale factor and offset provided. See the External Calibration section. In the MIC3000, this register will always return zero. This register is provided for compliance with SFF-8472. It is not used by the MIC3000 when doing threshold comparisons and setting alarm or warning bits. Transmitted Optical Power MSB (TXOPh)(4) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read-only read-only read-only read-only read-only read-only read-only read-only Default Value 0000 0000b = 00h (0mW)(5) Serial Address A2h = 1010001b Byte Address 102 = 66h Each LSB represents 25.6 µW. This register is to be used in conjunction with TXOPl to yield a sixteen-bit value. The values in TXOPh:TXOPl are in an unsigned binary format. The value in this register is uncalibrated. The host should process the results using the scale factor and offset provided. See the External Calibration section. Transmitted Optical Power LSB (TXOPl) D[7] D[6] D[5] D[4] D[3] D[2] D[1] D[0] read-only read-only read-only read-only read-only read-only read-only read-only Default Value 0000 0000b = 00h (0mW) Serial Address A2h = 1010001b Byte Address 103 = 67h Each LSB represents 0.1 µW. This register is to be used in conjunction with TXOPh to yield a sixteen-bit value. The values in TXOPh:TXOPl are in an unsigned binary format. The value in this register is uncalibrated. The host should process the results using the scale factor and offset provided. See the External Calibration section. In the MIC3000, this register will always return zero. This register is provided for compliance with SFF-8472. It is not used by the MIC3000 when doing threshold comparisons and setting alarm or warning bitsection. Notes: 3. ILDh will contain measured data after one A/D conversion cycle. 4. The scale factor corresponding to the sense resistor used must be set in the configuration register. 5. TXOPh will contain measured data after one A/D conversion cycle. |
