64-bit Digital I/O offers high-performance digital I/O wherever your application needs it The Keysight Technologies, Inc. L4450A is a high-speed 64-bit digital I/O instrument that is LXI Class C compliant. With its small size and Ethernet connectivity, the Digital I/O can be placed wherever your application needs it. The Keysight L4450A has 64 bi-directional lines configured as eight 8-bit channels. Each 8-bit channel has programmable polarity and thresholds up to 5 V. The 128 k of memory is useful for simulating and captur - ing digital patterns up to 10 MHz. The configurable handshaking protocols can be used for a wide variety of applications. In addition, the two 10 MHz counter channels can be used to count events, frequency, period, duty cycle, pulse width and totalize. Using this LXI instrument, you’ll get all the benefits of an Ethernet connection, built-in instrument web interface, standard software drivers and more. The LXI standard is supported by multiple vendors, enabling lower cost of test with accelerated test integration and development. – LXI compliance includes built-in Ethernet connectivity – Fully-featured graphical web interface – 64 bi-directional digital I/O bits with programmable polarity – Variable thresholds from 0 V to 5 V – Handshaking protocols – Source/sink current up to 24 mA – 128 kbytes pattern memory – Two 10 MHz counter channels – 20 MHz divide-by-n clock – Software drivers for most common programming environments Introduction

Digital inputs and outputs for your most complicated digital

applications

The L4450A can be used to simulate or detect digital patterns. It has eight 8-bit digital I/O channels with handshaking, pattern memory, two 10 MHz counters with gate functions, and a program- mable clock output. Digital input/output The digital I/O bits are organized into two banks of 32-bits. The I/O bits can be configured and programmed as inputs or outputs in 8-bit channels. The digital outputs can be configured as active drive or open drain outputs with a user supplied 10 kΩ pull up. User supplied pull-up resistors for up to 5 V outputs are also acceptable. The digital inputs have programmable thresholds up to 5 V for compatibility with most digital logic standards. The on-board pattern memory can be used to select and output digital stimulus or bit stream patterns, or to capture external digital data. Each bank has independent memory and directional control so that one bank can output data while another captures data. The memory can be di- vided up to 64 kbytes per 8-bit channel. The digital channels also have: – Variable active high drive output from 1.65 V to 5 V or open drain – Variable input thresholds from 0 V to 5 V – Configurable handshaking proto - cols including synchronous and strobe – Programmable polarity – Source or sink up to 24 mA – Internal alarming for maskable pattern match – 1 hardware pattern interrupt per bank External trigger capabilities make it easy or you to time and synchronize measurements and other events. This can help you determine when to begin or end an acquisition. The memory can be allocated as follows: Default configuration Memory on channels 1 & 2 Memory on channel 1 Channel 1/5 (bits 7:0) (bits 39:32) 32 kbytes 64 kbytes 64 kbytes Channel 2/6 (bits 15:8) (bits 47:40) 32 kbytes 64 kbytes Channel 3/7 (bits 23:16) (bits 55:49) 32 kbytes Channel 4/8 (bits 31:24) (bits 63:56) 32 kbytes
