# Local Bus

The local bus on a PXI backplane is a daisy-chained bus that connects each peripheral slot with adjacent peripheral slots to the left and right. The quantity of local bus lines is decreased from thirteen to one (PXI\_LBL6 and PXI\_LBR6) on a PXI Express backplane. The remaining local bus lines can transmit analog or digital signals between modules.

# Trigger Bus

Three trigger bus segments on the PXES-2785 consist of a first segment from 1st to 6th slots, a second from 7th to 12th slots, and a third from 13th to 18th slots, with each trigger bus segment containing 8 trigger lines connecting all slots on the same segment, providing inter-module synchronization. PXI and PXI Express modules can exchange trigger or clock signals through the trigger bus, allowing precisely timed response to asynchronous external events.

Trigger bus bridges can be configured as connected or disconnected (default) for the trigger lines of adjacent segments. As shown, eight combinations of trigger bus segment connections are possible between the three bus segments, with any applicable to each of the eight trigger lines.

# Reference Clock

The PXES-2785 backplane supplies a single-ended 10MHz reference clock (PXI\_CLK10) and differential 100MHz clock (PXIe\_CLK100) to each peripheral slot for inter-module synchronization. The independent buffers drive the clock signal to each peripheral slot.

These common reference clock signals can synchronize multiple modules in a PXI Express chassis. PXI modules with phase-lock loop circuits can lock reference clocks to generate an in-phase timebase.

The PXI\_CLK10 and PXIe\_CLK100 clocks are in-phase according to the PXI-5 specification. Since the external 10MHz clock input can override the onboard 10MHz clock source, a phase-lock loop (PLL) circuit on the backplane synchronizes the PXIe\_CLK100 and external 10MHz clock.

The PXES-2785 PXI chassis automatically selects the 10 MHz reference clock source from among:

 Built-in accurate 10 MHz clock source
 External 10 MHz clock through a BNC connector
 PXI\_CLK10\_IN pin on the system timing slot (slot 10)

Priorities for 10MHz reference clock are as follows.

<table><tr><td>System Timing Slot (10th slot)</td><td>BNC Connector on Rear Panel</td><td>10mhz Clock Driven to Peripheral Slots</td></tr><tr><td>No clock present</td><td>No clock present</td><td>10MHz clock is generated by backplane</td></tr><tr><td>No clock present</td><td>10MHz clock present</td><td>Clock from BNC connector is driven to all peripheral slots</td></tr><tr><td>10MHz clock present</td><td>No clock present</td><td>Clock from system timing slot is driven to all peripheral slots</td></tr><tr><td>10MHz clock present</td><td>10MHz clock present</td><td>Clock from system timing slot is driven to all peripheral slots</td></tr></table>

# 2.2 Power Supply Budget Considerations

Please review the power consumption of all modules used in the same PXES-2785. The total maximum power consumed by the system module and peripheral modules shall not exceed the DC power supply of the PXES-2785 as defined in DC Power Output on page 4 and Backplane Slot DC Power Current on page 4.

# 2.3 Cooling Considerations

The PXES-2785 features an innovative design for heat dissipation, with cooling fans in the rear section of the chassis, drawing cool air through apertures on the bottom for exhaust through the back. This design provides uniform airflow for each PXI slot and exceptional cooling capability. When the chassis is installed in a rack, the cooling design minimizes drawing of hot air from the rear area, where other devices exhaust, while maintaining a steady temperature inside the chassis. For optimal cooling efficiency, retain support feet.

When rack mounting the PXES-2785, at least 1U (44.5 mm/1.75 in.) clearance below the intake apertures is required. Also keep other objects or equipment at a minimum of 44.45 mm (1.75 in.) away from the outlet apertures in the rear of the chassis.
