Transmitter (Tx) Output Characteristics
This section discusses the Gen1i/1.5G and Gen2i/3G transmitter output characteristics for the SATA
interface.
16.2.1
Gen1i/1.5G Transmitter Specifications
Table 54 provides the DC differential transmitter output DC characteristics for the SATA interface at
Gen1i or 1.5 Gbits/s transmission.

Note:
1 Only 100/125/150 MHz have been tested, othe in between values will not work correctly with the rest of the system.
2 In a frequency band from 150 kHz to 15 MHz at BER of 10-12.
3 Total peak to peak Deterministic Jitter "D
J" should be less than or equal to 50 ps.
