PI3EQX4951ST 3.3V, 1-port, SATA2 i/m ReDriver™ with Analog/Digital Configuration Features Description ÎÎSATA2 i, m; external SATA2 Pericom Semiconductor’s PI3EQX4951ST is a low power, signal ReDriver™. The device provides programmable equalization, to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. PI3EQX4951ST supports two 100-Ohm Differential CML data I/O’s between the Protocol ASIC to a switch fabric, across a backplane, or to extend the signals across other distant data pathways on the user’s platform. ÎÎTwo 3.0Gbps differential signal pairs ÎÎIndependent Digital Output Emphasis Control ÎÎ100-Ohm Differential CML I/O’s ÎÎInput signal level detect and squelch for each channel ÎÎOOB Support The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver. ÎÎEnhanced Mode Features: àà Adjustable Receiver Equalization àà Independent Analog Output Emphasis Control ÎÎHigh impedance I/O termination in standby mode A low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully independently. When the channels are enabled (EN=1) and operating, that channels input signal level (on xI+/-) determines whether the output is active. If the input signal level of the channel falls below the active threshold level (Vth-) then the outputs are driven to the common mode voltage. ÎÎLow Power Operation: 300mW typical ÎÎAuto-Slumber Mode: 33mW typical ÎÎPower down Stand-by Mode: 0.1mW ÎÎSupply Voltage: 3.3V ±10% In addition to signal conditioning, when EN = 0, the device enters a low power standby mode. 20-TQFN (4x4mm) GND Signal Detection GND VDD Standard Mode (MODE = 0) NC Pin Diagram (Top Side View) Block Diagram MODE ÎÎPackaging: 20 19 18 17 16 AO+ NC 2 3 14 13 NC BO- 4 BO+ 5 BIBI+ 8 9 10 Enhanced Mode (MODE = 1) VDD A_EM A_EQ MODE NC - Repeated 2 times - Control Circuit 12 11 AO- A_EM VDD xO- Power Management 6 7 Limiting Amp xl- EN GND NC Equalizer xO+ 15 AI- B_EM CML xl+ 1 EN CML AI+ x_EQ x_EM AI+ 1 AI- 2 3 NC BO- GND 6 7 8 9 10 15 14 AO+ AONC 13 12 BI- 11 BI+ NC EN B_EQ B_EM VDD BO+ 4 5 20 19 18 17 16 10-0142 1 www.pericom.com PS9072A 03/23/10 PI3EQX4951ST 3.3V, 1-Port, SATA2 i/m ReDriver™with Analog/Digital Configuration Pin Description Standard Enhanced Mode Pin Mode Pin # # Pin Name Type Description Output emphasis adjustment for channel A.
