Stress beyond “ Absolute Maximum Range” may cause permanent damage to the device.
Note 1: Except Data retention. Data retention is prescribed at section-% (2) EEPROM.

Note 1: without BIAS and modulation current
Note 2: I-DAC1 = 0, I-DAC2 = 0, Gain = 1, PDGAIN = 0dB, PDIN = 1V
Note 3: DATAP = CLKP = “ L” , DATAN =CLKN = “ H”
Note 4: 155.52Mbps, PN7
Note 5: I-DAC1 = I-DAC2 = FFh (Full code), Gain = 1, PDGAIN = 0dB, PDIN = 1V
2. EEPROM
Note 1: This parameter is characterized and is not 100% tested.
Important Notice: The AKM factory adjusted data are stored in advance at address location (Device Address = A6h,
Address = 60h) for the offset of the on-chip temperature sensor. If such excess temperature stress is to be applied to
the AK2573A which exceeds a guaranteed EEPROM data retention conditions (for 10 years at 85C), it is important to
read the pre-determined value in advamce and to re-write the same data back into EEPROM after an exposure to the
excess temperature environment. Even if the exposure time is shorter than the retention time, any accelerated
temperature stress tests (such as baking) are performed, it is recommended to read the pre-set data first and to
re-write it after the test. Access to un-used address locations is not functionally guaranteed.
Refer to section- 8.3 for EEPROM map.
