The SN65HVD63 transceiver modulates and demodulates signals between the logic (baseband) and a frequency
suitable for long coaxial media. The SN65HVD63 device is an integrated AISG transceiver designed to meet the
requirements of the upcoming Antenna Interface Standards Group v3.0 specification. 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.

9.3 Feature Description
9.3.1 Coaxial Interface
The SN65HVD63 transceiver enables the transfer of data between radio equipment by modulating baseband
data to a carrier frequency of 2.176 MHz (per the AISG standard). The transmitter output amplitude can be
configured from 0 dBm to 6 dBm in order to communicate over a variety of different links, and the output
emissions spectrum is designed to be compliant to AISG limits. The receiver features an active bandpass filter
circuit that helps to separate the carrier frequency data from other spurious frequency components.
9.3.2 Reference Input
The 2.176-MHz modulation frequency is derived from an input reference that is nominally 8.704 MHz. The input
reference can come either from a crystal or from an oscillator circuit with a tolerance of up to 30 ppm.
9.3.3 RS-485 Direction Control
To facilitate bus arbitration of an RS-485 interface, the SN65HVD63 provides a direction control output that can
be used to control the enable/disable controls of an RS-485 transceiver. The direction control output
automatically toggles based on activity present on the coaxial input interface, and has an adjustable time
constant (controlled by the DIRSET1 and DIRSET2 pins) in order to accommodate various signaling rates.

9.4 Device Functional Modes
If DIRSET1 and DIRSET2 are in a logic high state, the device will be in standby mode. While in standby mode,
the receiver functions normally, detecting carrier frequency activity on the RXIN pin and setting the RXOUT state.
The transmitter circuits are not active in standby mode, thus the TXOUT pin is idle regardless of the logic state of
TXIN. The supply current in standby mode is significantly reduced, allowing power savings when the node is not
transmitting.
When not in standby mode, the default power-on state is idle. When in idle mode, RXOUT is high, and TXOUT is
quiet. The device transitions to receive mode when a valid modulated signal is detected on the RXIN line or the
device transitions to transmit mode when TXIN goes low. The device stays in either receive or transmit mode
until DIR time-out (nominal 16 bit times) after the last activity on RXOUT or TXIN.
When in receive mode:
•
RXOUT responds to all valid modulated signals on RXIN, whether from the local transmitter, a remote
transmitter, or long noise burst.
•
TXOUT responds to TXIN, generating 2.176-MHz signals on TXOUT when TXIN is low, and TXOUT is quiet
when TXIN is high. (In normal operation, TXIN is expected to remain high when the device is in receive
mode.)
•
The device stays in receive mode until 16 bit times after the last rising edge on RXOUT, caused by valid
modulated signal on the RXIN line.
When in transmit mode:
•
•
RXOUT stays high, regardless of the input signal on RXIN.
TXOUT responds to TXIN, generating 2.176-MHz signals on TXOUT when TXIN is low, and TXOUT is quiet
when TXIN is high.
•
The device stays in transmit mode until 16 bit times after TXIN goes high.

10 Application and Implementation
注
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
10.1 Application Information
10.1.1 Driver Amplitude Adjust
The SN65HVD63 device can provide up to 2.5 V of peak-to-peak output signal at the TXOUT pin to compensate
for potential loss within the external filter, cable, connections, and termination. External resistors are used to set
the amplitude of the modulated driver output signal. Resistors connected across RES and BIAS set the output
amplitude. The maximum peak-to-peak voltage at TXOUT is 2.5 V, corresponding to 6 dBm on the coaxial cable.
The TXOUT voltage level can be adjusted by choice of resistors to set the voltage at the RES pin. according to
the following equation:
VTXOUT (VPP) = (2.5 VPP × VRES (V)) / 1.5 V VRES (V) = 1.5 V × R2 / (R1 + R2) VTXOUT (VPP) = 2.5 VPP × R2 / (R1 + R2)
(1)
The voltage at the RES pin should be from 0.7 V to 1.5 V. Connect RES directly to the BIAS (R1 = 0 Ω) for
maximum output level of 2.5 VPP. This gives a minimum voltage level at TXOUT of 1.2 VPP, corresponding to
about 0 dBm at the coaxial cable. A 1-μF capacitor should be connected between the BIAS pin and GND. To
obtain a nominal power level of 3 dBm at the feeder cable as the AISG standard requires, use R1 = 4.1 kΩ and
R2 = 10 kΩ that provide 1.78 VPP at TXOUT.
10.1.2 Direction Control
In many applications the mast-top modem that receives data from the base distributes the received data through
an RS-485 network to several mast-top devices. When the mast-top modem receives the first logic 0 bit (active
modulated signal) it takes control of the mast-top RS-485 network by asserting the direction control signal. The
duration of the direction control assertion should be optimized to pass a complete message of length B bits at the
known signaling rate (1/tBIT) before relinquishing control of the mast-top RS-485 network. For example, if the
messages are 10 bits in length (B=10) and the signaling rate is 9600 bits per second (tBIT = 0.104 ms) then a
positive pulse of duration 1.7 ms is sufficient (with margin to allow for network propagation delays) to enable the
mast-top RS-485 drivers to distribute each received message. 图 23 shows the assertion of direction control.
Coax In
Data Out
Direction
图 23. Assertion of Direction Control
10.1.3 Direction Control Time Constant
The time constant for the direction control function can be set by the control mode pins, DIRSET1 and DIRSET2.
These pins should be set to correspond to the desired data rate. With no external connections to the control
mode pins, the internal time constant is set to the maximum value, corresponding to the minimum data rate.

10.1.4 Conversion Between dBm and Peak-to-Peak Voltage
dBm = 20 × LOG10 [Volts-pp / SQRT(0.008 × Zo)] = 20 × LOG10 [VPP / 0.63] for Zo = 50 Ω
VPP = SQRT(0.008 × Zo) × 10(dBm/20) = 0.63 × 10(dBm/20) for Zo = 50 Ω

图 24. Typical AISG Application
10.2.1 Design Requirements
An AISG transceiver is used to convert between digital logic-level signals and RF signals. The AISG standard
requires an RF carrier frequency of 2.176 MHz with 100-ppm accuracy. The output signal of the driver, when
active, should be from 1 dBm to 5 dBm. The receiver must be designed such that the input threshold is from –18
dBm to –12 dBm.
10.2.2 Detailed Design Procedure
To ensure accuracy of the carrier frequency, an input reference frequency equal to four times the carrier (that is,
8.704 MHz) should be connected to the XTAL1 or XTAL2 inputs. This signal can come from a crystal (connected
between XTAL1 and XTAL2) or from a PLL/clock generator circuit (connected to XTAL1 with XTAL2 grounded).
The frequency accuracy must be within 100 ppm.

Typical Application (接下页)
The driver output power level of the SN65HVD63 device can be adjusted through use of the RES pin. To align
with AISG requirements, a nominal power level of 3 dBm should be configured by connecting a 4.1-kΩ resistor
between RES and BIAS and a 10-kΩ resistor between RES and GND. 图 25 shows an example schematic.

11 Power Supply Recommendations
The SN65HVD63 device has two power supply pins: VCC, which provides power to the analog circuitry, and VL,
which is a logic supply. VCC should be operated from 3 V to 5.5 V, while VL can range from 1.6 V to 5.5 V to
interface to different logic levels. Power supply decoupling capacitances of at least 0.1 µF should be placed as
close as possible to each power supply pin.
12 Layout
12.1 Layout Guidelines
Best practices for high-speed PCB design should be observed because the coax interface to the SN65HVD63
device operates at RF. The RF signaling traces should have a controlled characteristic impedance that is well-
matched to the coaxial line. A continuous reference plane should be used to avoid impedance discontinuities.
Power and ground distribution should be done through planes rather than traces to decrease series resistance
and increase the effective decoupling capacitance on the power rails.
