Description
VCO1 tank inductance, negative side. Used to complete resonant circuit for
VCO1. Refer to the applications section of the datasheet for details.
VCO1 tank inductance, positive side. Used to complete resonant circuit for
VCO1. Refer to the applications section of the datasheet for details.
VCO1 regulator output. A decoupling capacitor is required to ground. DC
output voltage of approximately 1.4V when VCO1 is enabled.
This pin should be tied to ground.
VCO2 regulator output. A decoupling capacitor is required to ground. DC
output voltage of approximately 1.4V when VCO2 is enabled.
Oscillator buffered output mode control. This pin controls the frequency of
the OSCO (pin 48) output. A logic 0 on this pin results in 13MHz output and
a logic 1 results in a 26MHz output. Digital input with weak pulldown.
Oscillator mode control. This pin controls the internal reference oscillator
mode as described in the Reference Oscillator section. Digital input with
weak pulldown.
Digital serial RX data interface output for Q data. This pin provides the Q
data while in digital RX interface mode and RXMODE(2:0) is set to 001 or
110. When S_MODE is low or RXMODE(2:0) is not equal to 001 or 110, this
pin can be multiplexed and used as a third general purpose output(GPO3).
This GPO can be used to control a T/R switch. Digital output.
Digital serial RX data interface output or QB analog output. This pin is mul-
tiplexed between analog and digital RX output modes. The S_MODE bit
sets the interface mode. Digital output or buffered analog output.
Digital serial RX data interface frame sync or Q analog output. This pin is
multiplexed between analog and digital RX interface modes. The S_MODE
bit sets the interface mode. The RXFSB bit determines the direction of the
pin in digital mode. Digital input, digital output, or buffered analog output.
Digital serial RX data interface clock or IB analog output. This pin is multi-
plexed between analog and digital RX output interface modes. The
S_MODE bit sets the interface mode. The RXCKB bit determines the direc-
tion of the pin in digital mode. Digital input, digital output, or buffered ana-
log output.
