Texas Instruments has introduced a fully-integrated, on-off keying modem transceiver that is compliant with the Antenna Interface Standards Group (AISG) v2.0 specification. TI claims SN65HVD62 reduces power consumption by up to 50 percent compared to the competition. The transceiver modulates and demodulates signals between the logic (baseband) and a frequency suitable for long coaxial media such as AISG coaxial links between base station and tower- mounted equipment, tower-mounted amplifiers, remote electrical tilt units and control links on microwave towers.
SN65HVD62 consumes 33-mA supply current in standby mode. SN65HVD62 integrates all the components required to transmit and receive signals, including an active band-pass filter to demodulate signals even in the presence of spurious frequency components, into a 3-mm by 3-mm package. SN65HVD62 supports adjustable output power levels, varying from 0 dBm to 6 dBm delivered to the 50-ohm coax cable.
SN65HVD62 produce lower emissions in the RF band.
The SN65HVD62 provides a direction output, for easy control of half-duplex, RS-485 transceivers, such as the SN65HVD72, which is compatible with the 115-kbps signaling rate used in AISG networks. This combination provides the lowest-power link between the base station and multiple pieces of tower-mounted equipment.
Availability, packaging and pricing: The SN65HVD62 is available in industry-standard, 16-pin QFN package. Suggested retail pricing in 1,000-unit quantities is US$2.00.
