CA-IF4023

The CA-IF4023 is an integrated AISG transceiver which is compliant with the Antenna Interface Standards Group v3.0 specification. Integrated on the chip are the transmitter, receiver, and active filters. This device reduces the hassle and expense of working with discrete solutions and drastically reduces the time needed to implement the AISG protocol.

The receive channel offers a typical dynamic range of 20dB and integrates an active bandpass filter to enable demodulation of signals even in the presence of spurious frequency components. The filter has a 2.176MHz center frequency.

The transmitter integrates an narrow bandwidth bandpass filter with 2.176MHz center frequency as well, compliant with the spectrum emission requirement provided by the AISG standard. It supports adjustable output power levels varying from +5.4dBm to +12dBm in order to compensate for loss in the external circuitry and cabling.

A direction output is provided which facilitates bus arbitration for the RS-485 communication interface. Also, the CA-IF4023 device integrates an oscillator input for a crystal and accepts standard clock input to the oscillator.

The CA-IF4023 is packaged in a small, 3mm x 3mm, 16-pin QFN and is fully specified for operation over -40°C to +125°C extended industrial temperature range."
