DescriptionThe DS64BR401SQ is a quad lane bi-directional signal conditioning repeater for 6.0/3.0/1.5 Gbps SATA/SAS and other high-speed bus applications with data rates up to 6.4 Gbps. The device performs both receive equalization and transmit deemphasis on each of its 8 channels to compensate for channel loss, allowing maximum flexibility of physical placement within a system.
The features of DS64BR401SQ can be summarized as:(1)Quad lane bi-directional repeater up to 6.4 Gbps rate; (2)Signal conditioning on input and output for extended reach; (3)Adjustable receive equalization up to +33 dB gain; (4)Adjustable transmit de-emphasis up to -12 dB; (5)Adjustable transmit VOD (600 mVp-p to 1200 mVp-p); (6)<0.25 UI of residual DJ at 6.4 Gbps with 40" FR4 trace; (7)Automatic de-emphasis scaling based on rate detect; (8)SATA/SAS: OOB signal pass-through, <3 ns (typ) envelope distortion; (9)Adjustable electrical IDLE detect threshold; (10)Low power (100 mW/channel), per-channel power down; (11)Programmable via pin selection or SMBus interface; (12)Single supply operation at 2.5V ±5%; (13)>6 kV HBM ESD Rating; (14)3.3V LVCMOS input tolerant for SMBus interface; (15)High speed signal flowthru pinout package: 54-pin LLP (10 mm x 5.5 mm).
The absolute maximum ratings of DS64BR401SQ are:(1)Supply Voltage (VDD):-0.5V to +3.0V; (2)LVCMOS Input/Output Voltage:-0.5V to +4.0V; (3)CML Input Voltage:-0.5V to (VDD+0.5V); (4)LPDS Output Voltage:-0.5V to (VDD+0.5V); (5)Analog (SD_TH):-0.5V to (VDD+0.5V); (6)Junction Temperature:+125°C; (7)Storage Temperature:-40°C to +125°C; (8)Maximum Package Power Dissipation at 25°C:SQA54A Package 4.21 W; (9)Derate SQA54A Package 52.6mW/°C above +25°C; (10)HBM, STD - JESD22-A114C 6 kV; (11)MM, STD - JESD22-A115-A 250 V; (12)CDM, STD - JESD22-C101-C 1250 V; (13)Thermal Resistance:JC..11.5°C/W,JA, No Airflow, 4 layer JEDEC..19.1°C/W.
