transmitter provides for design flexibility
Code Hopping Encoder:
Programmable minimum code word completion
Battery low signal transmitted to receiver with pro-
grammable threshold
Non-volatile EEPROM storage of synchronization
data
Easy to use EEPROM programming interface
PWM or Manchester modulation
Selectable encoder data rate 417 to 3334 bps
On-chip tunable encoder oscillator
RF Enable output for transmitter control
Button inputs have internal pull-down resistors
Elapsed time and button queuing options
Current limiting on LED output
2-bit CRC for error detection
UHF ASK/FSK Transmitter:
Conforms to US FCC Part 15.231 regulations and
European ERC 70-03E and EN 300 220-1
requirements
VCO phase locked to quartz crystal reference;
allows narrow receiver bandwidth to maximize
range and interference immunity
Crystal frequency divide by 4 output (CLKOUT)
Transmit frequency range (310 – 440 MHz) set by
Crystal frequency
ASK Modulation
FSK Modulation through crystal pulling
(rfHCS362F)
Adjustable output power: -12 dBm to +2 dBm
Differential output configurable for single or
double ended loop antenna
Automatic power amplifier inhibit until PLL lock
Pin Diagrams
