Things breeds new things in innovation, and best replacement old thing is selected in the survival of the fittest.
The interface of hard disk develops similarly in this way, needs the development for accelerating to adapt to the progress of other products.Current solid-state
Mainly based on SAS, SAS buses use embedded clock signal to the interface that hard disk is applied, and possess higher error correcting capability,
The difference of its maximum compared with the past is can be to transmission instruction（Not exclusively data）Checked, if it find that mistake can be certainly
Dynamic correction, something which increases the reliability of data transfer.
Serial line interface also has the advantages that simple structure, supports hot plug.But SAS limits the transmission speed of hard disk
In 300 MB/s（Write）、500 MB/s（Read）This rank is difficult to be lifted again, cannot meet consumer to hard disk speed
Expectation.
And PCIE interfaces can bring up to one data transmission rate
Very high frequency, reaches the SAS high bandwidths to be provided, thus SSD walk PCIE interfaces have one it is most direct
Benefit, breaks through the transmission speed of mono- 600 MB/s of the current Gbps of SAS 6.0.
Nowadays, it is proposed much using the product of PCIE SSD, in performance, possesses the ultimate attainment read-write effect for surmounting imagination
Energy.Chip manufacturer is also strongly promoting PCIE SSD, and future has been trend of the times using PCIE SSD, but at present industry is also

The Pin sequences definition of Connector, TX signals, CLK signal and RX signals are drawn, and TX signals, RX signals are connected to SNP
On Connector, CLK signal is firstly connected on SNP Connector, is then attached to Switch switching circuits.
Further, the TX signals, RX signal Jing PCB traces are connected to P, the N-terminal of correspondence SNP Connector.
Further, CLK signal Jing PCB traces first are connected to P, the N-terminal of correspondence SNP Connector, then
Jing PCB traces are connected to Switch switching circuits.
Further, the PCB trace is the differential signal line of 100 ohm impedance matchings, P, N of each pair differential signal line
Length discrepancy is controlled within 1 mil.
Further, NVME Connector fixing holes are reserved on the pcb board, NVME Connector are welded on PCB
On the reserved NVME Connector fixing holes of plate.
Further, SNP Connector fixing holes are reserved on the pcb board, SNP Connector are welded on pcb board
On reserved SNP Connector fixing holes.
Further, the Switch switching circuits include Switch switching devices and pull-up electric capacity.
A kind of improved NVME SSD measurement jigs of the present utility model, compared with prior art produced beneficial effect
It is：
This utility model meets the NVME Connector of PCIE interface standards using the pcb board of a bilayer in welding.
Pin sequences according to NVME Connector are defined, and TX, RX and CLK signal are drawn, and TX/RX signals are connected directly between SNP
On Connector, CLK signal is connected to first on SNP Connector, behind increase Switch switching circuits.This practicality is new
Type directly can be connected in test equipment by SNP cables, realize measurement, the debugging of PCIE signal quality；Using SNP
Connector, take up room reduction, saves PCB costs；Possess speed handover module, can comprehensively cover the test of PCIE signal,
And do not coordinate by external device, the research and development and debugging for PCIE SSD products provide strong technical support.
