RFM offers a full set of custom embedded wireless networking solutions like Zigbee wireless mesh sensor networks, RF modules, IC transceiver, IC transmitters and IC receivers. RFM, Inc. manufactures low power wireless and RF radio modules, wireless mesh nodes for distributed sensing on distributed sensor networks. Low Power radio, n../arrowband and short range devices, front end saw filters, active RFID, RFIC, coupled resonator filters, single silicon chips in the 70MHZ and 300-1000Mhz range.
The output of this device is generated and filtered by narrow-band quartz SAW elements at 669.327 MHz.
The configuration of this clock provides a pure signal for optical timing applications in noisy signal
environments. The Q/Q differential output swing of ±1 volt about 0 Vdc has symmetry better than ±1% into
loads from 40 to 70 ohms, determined by customer application. The long term frequency accuracy is set by
an external reference source allowing this device to complete a Phase Lock Loop design without the usual
noise and jitter problems associated with PLL’s.
