Specifications, Features, Applications

Device Types Available for Test Instrumentation and Simulation Equipment Requiring Mil-Std-1553A/B, MacAir A5232, A5690 Interfaces. Controllable Output Voltage Provides Capability to Automate the Remote Terminal Validation and Production Test Plans. Very Low Standby Power Totally Isolated Channels Short Circuit Proof Superior Noise Performance

The NHI variable output voltage transceivers are available in both single and dual channel, +12V and +15V power supply source, and packaged in both plug-in and surface mount package styles. Each receiver converts the 1553 bus bi-phase data to complementary RX and RX_L TTL digital outputs for use by the manchester decoder. The device provides independent receiver enables for each channel. The transmitters will output bi-phase manchester to the coupling transformer when the TX and TX_L inputs are driven by complementary TTL digital data. The device provides an independent transmitter inhibit TXINH for each channel. The transmitter output voltage to the data bus is controlled by a single control voltage input pin.

The NHI-1540 requires a transformer with a turns ratio of 1.25:1.00 for Direct Coupling, and a turns ratio of 1.66:1.00 for Transformer Coupling to the Mil-Std-1553 Bus. Technitrol part number Q1553-3 or equivalent is recommended. The center tap on the transceiver side of the isolation transformer must be grounded.
