The SN65HVD63 transceiver modulates and demodulates signals between a logic (baseband) interface and a frequency suitable for long coaxial media, to facilitate wired data transfer among radio equipment.
The SN65HVD63 receiver integrates an active bandpass filter to enable demodulation of signals even in the presence of spurious frequency components. The filter has a 2.176-MHz center frequency.
The transmitter supports adjustable output power levels from 0 dBm to 6 dBm delivered to the 50-Ω coax cable. The SN65HVD63 transmitter is compliant with the spectrum emission requirement provided by the AISG standard.
A direction control output facilitates bus arbitration for an RS-485 interface. This device integrates an oscillator input for a crystal, and also accepts standard clock inputs to the oscillator.
