Provides start-of-data detection and data clock recovery
Supports data rates from 2400 to 19200 bps
Allows unsquelched receiver operation for improved sensitiviy
Compatible with RFM’s TR-Series ASH transceivers
Data/Clock
Extraction
IC
The IC1000 Data/Clock Extraction IC detects a start-of-data pulse sequence and then provides clocking
pulses in the middle of each following data bit. The IC1000 is designed to support a host protocol processor
which can be in sleep mode until interrupted into active operation by the start-of-data detect pulse. The
IC1000 is compatible with RFM's 2nd generation ASH transceivers and receivers and allows these radios to
operate with no threshold for improved system sensitivity.
