1. Introduction
Overview
PXIe-2519 is a high performance cost-effective 9-slot all hybrid PXI/PXIe chassis. It
complements JYTEK PXIe-62509 9-slot sturdy all hybrid chassis with the new
mechanical design that appeals to customers who wish to lower system cost but
retain the high performance.
Depanding on PCIe link speed capability, PXIe-2519 series provide two models as
shown in Table 1.
Table 1 PXIe-2519 series model name
Note:
system bandwidth defined as data rate between controller and chassis
backplane.
slot bandwidth defined as data rate between peripheral module and chassis
backplane.
Main Features
High data throughput 9-slot PCIe Gen2 (PXIe-2519G2) or Gen3 PXIe chassis
(PXIe-2519G3)
High clock accuracy and low phase jitter
Low power ripple noise
Specially designed for cost effective PXI/PXIe applications
Ideal for OEM vendors

2.1.2 System Controller Slot
The System Controller slot is a fixed PCIe 4-Link configuration. Link 1, 2 and 3 are
routed to slot2, slot3 and slot4 repectively. Link 4 is routed to PCIe switch and
downstream to slot5~slot9 and PCI bus. The chassis can accommodate a maximum
4-slot width PXIe controller.
2.1.3 Peripheral Slot
PXIe-2519 provides eight hybrid peripheral slots. It can accept the following
peripheral modules:
PXI Express Peripheral Module
CompactPCI Express Type-2 Peripheral Module
Hybrid slot compatible PXI-1 Peripheral Module
CompactPCI 32-bit Peripheral Module
Figure 3 PXIe-2519 Peripheral Slot Compatible Modules
Each peripheral slot PCIe link can support Gen3 x4 (PXIe-2519G3) or Gen2 x4
(PXIe-2519G2), providing maximum single-direction bandwidth of 4GB/s or 2GB/s.
And each peripheral slot can also support 32bit PCB bus, providing maximum
single-direction bandwidth of 132MB/s.

2.1.4 PXI Trigger Bus
All slots on PXIe-2519 share eight trigger lines, peripheral module can deliver trigger
or clock via the trigger bus to synchronize the data acquisition operation.
2.1.5 PXI Local Bus
The local bus on PXIe-2519 is a daisy-chained bus that connects each peripheral slot
with adjacent peripheral slots to the left and right, which by routing PXI Local Bus 6
signal between adjacent peripheral slots.
2.1.6 System Reference Clock and Synchronization Signal
The PXIe-2519 supplies 10MHz reference clock (PXI_CLK10), 100MHz reference clock
(PXIe_CLK100) and synchronization signal (PXIe_SYNC100) to each peripheral slot for
inter-module synchronization.
The PXIe-2519 has the default timing relationship of PXI_CLK10, PXIe_CLK100 and
PXIe_SYNC100 as show in Figure 4 which comply with PXI-5 specification.

2.4.4 Fan Mode
PXIe-2519 provides the smart fan control mechanism as blow curve. It provides two
fan modes.
Table 4 Fan Mode
When the Fan Switch is set to AUTO mode, the fan speed is controlled based on the
measured temperature of sensor.
Fans run at 40% duty cycle if the measured temperature less than 40°C, and begin
ramping up when any temperature reading exceeds 40°C.
Fans run at 100% duty cycle (full speed) if any temperature reading exceeds 65°C.
When the Fan Switch is set to HIGH mode, fans run at 100% duty cycle immdiately.
The factory default fan control curve shows as following Figure.

Chassis Cooling Considerations
2.5.1 PXI/PXIe Modules Cooling
For PXI/PXIe modules cooling, there are two fans on the underside of the chassis
draw cool air from the bottom side of chassis to be exhausted to the top sides of the
chassis.
