DescriptionThe DS50PCI401SQ is a low power, 4 lane bidirectional buffer/equalizer designed specifically for PCI Express Gen1 and Gen2 applications. The device performs both receive equalization and transmit deemphasis, allowing maximum flexibility of physical placement within a system.
The features of DS50PCI401SQ can be summarized as:(1)Input and Output signal conditioning increases PCIe reach in backplanes and cables; (2)0.09 UI of residual deterministic jitter at 5Gbps after 42" of FR4 (with Input EQ); (3)0.11 UI of residual deterministic jitter at 5Gbps after 7m of PCIe Cable (with Input EQ); (4)0.09 UI of residual deterministic jitter at 5Gbps with 28" of FR4 (with Output DE); (5)0.13 UI of residual deterministic jitter at 5Gbps with 7m of PCIe Cable (with Output DE); (6)Adjustable Transmit VOD 800 to 1200mVp-p; (7)Automatic power management on an individual lane basis via SMBus; (8)Adjustable electrical idle detect threshold.; (9)Data rate optimized 3-stage equalization to 26 dB gain; (10)Data rate optimized 6-level 0 to 12 dB transmit deemphasis; (11)Flow-thru pinout in 10mmx5.5mm 54-pin leadless LLP package; (12)Single supply operation at 2.5V; (13)>6kV HBM ESD rating; (14)-10 to 85°C operating temperature range.
The absolute maximum ratings of DS50PCI401SQ 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)CML Input Current:-30 to +30 mA; (5)LPDS Output Voltage:-0.5V to (VDD+0.5V); (6)Analog (SD_TH):-0.5V to (VDD+0.5V); (7)Junction Temperature:+125°C; (8)Storage Temperature:-40°C to +125°C; (9)Lead Temperature Range Soldering (4 sec.):+260°C; (10)Maximum Package Power Dissipation at 25°C:SQA54A Package 4.21 W; (11)Derate SQA54A Package:52.6mW/°C above +25°C; (12)HBM, STD - JESD22-A114C 6 kV; (13)MM, STD - JESD22-A115-A 250 V; (14)CDM, STD - JESD22-C101-C 1250 V; (15)Thermal Resistance:JC..11.5°C/W,JA, No Airflow, 4 layer JEDEC..19.1°C/W.
