The device complies with SATA physical link 2m and 3i specifications. SN75LVCP601 operates from a single 3. 3-V supply and has 100- line termination with a self-biasing feature, making the device suitable for ac coupling. [. . . ] Exiting from this mode to normal operation requires a maximum latency of 5 µs. 6 Submit Documentation Feedback Product Folder Link(s): SN75LVCP601 Copyright © 2010, Texas Instruments Incorporated Vcc SATA Connector SN75LVCP601 www. ti. com SLLSE41 ­ JUNE 2010 2. Auto low-power mode (triggered when a given channel is in the electrically idle state for more than 100 µs and EN = Vcc) ­ The device enters and exits low-power mode by actively monitoring the input signal (VIDp-p) level on each of its channels independently. When the input signal on either or both channels is in the electrically idle state, i. e. , VIDp-p < 50 mV and stays in this state for >100 µs, the associated channel(s) enters into the low-power state. In this state, output of the associated channel(s) is driven to VCM and the device selectively shuts off some circuitry to lower power by >80% of its normal operating power. Exit time from the auto low-power mode is <50 ns. Out-of-Band (OOB) SUPPORT The squelch detector circuit within the device enables full detection of OOB signaling as specified in the SATA specification. Differential signal amplitude at the receiver input of 50 mVpp or less is not detected as an activity and hence not passed to the output. Differential signal amplitude of 150 mVp-p or more is detected as an activity and therefore passed to the output, indicating activity. Squelch circuit ON/OFF time is 5 ns, maximum. While in squelch mode, outputs are held to VCM. DEVICE POWER The SN75LVCP601 is designed to operate from a single 3. 3 V supply. Always practice proper power-supply sequencing procedure. Apply Vcc first, before any input signals are applied to the device. The power-down sequence is in reverse order.

These are stress ratings only, and functional operation of the device at these or any conditions beyond those indicated under Recommended Operating Conditions is not implied. The junction-to-board characterization parameter, yJB, estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining qJA , using a procedure described in JESD51-2a (sections 6 and 7). The junction-to-case (bottom) thermal resistance is obtained by simulating a cold plate test on the exposed (power) pad. No specific JEDEC standard test exists, but a close description can be found in the ANSI SEMI standard G30-88.
