PREOUT
Output
Prescaler Output. Usually connected to input of external low frequency
CMOS synthesizer (Fujitsu MB87006A, Siemens PMB2307, or similar).
Logic “1” turns on power to VCO, and divider/prescalers.
VBAT T connection for regulator. Normally connected to 3.3 V dc or battery.
Base connection to external regulator pass transistor (MMBT 3906 or similar).
Connection for VCO tank circuit (LC network).
Substrate ground connection.
Connection for VCO tank circuit (LC network).
Received Signal Strength Indicator output signal.
Accepts modulated transmit signal at 10.7 MHz IF.
Regulated VCC for LO from external pass transistor.
Logic “1” turns on power to LNA and receive mixer stages.
Input to limiting amplifier.
Input signal common for limiting amplifier.
Output of first stage of IF amplifier. Normally connected through 10.7 MHz
filter to Pin 12 (LIMIN).
Input to first stage of IF amplifier.
Local VCC connection for IF amp/limiter stages.
10.7 MHz IF Output. Normally connected through 10.7 MHz filter to IF
amplifier input (Pin 15).
Local ground for LNA.
Substrate ground connection.
LNA Input. Normally driven single-ended from 50
source impedance.
VCC for LNA.
Substrate ground connection.
10.7 MHz limiter output.
Local ground for PA stage emitter. Degeneration may be added.
T ransmitted RF output signal at 0 dBm level.
Local VCC connection for T X stages.
Logic “1” turns on power to transmit mixer, buffers, and PA stages.
Prescaler Modulus control (HIGH = divide-by-64; LOW = divide-by-65).
