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
This table provides the DC differential transmitter output DC characteristics for the SATA interface at
Gen1i or 1.5 Gbits/s transmission.

Notes:
1. Only 100/125/150 MHz have been tested, other 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 "DJ" should be less than or equal to 50 ps.
