AMIS-53050 Frequency Agile Transceiver
Data Sheet
In the low power mode (idle/stand-by), an internal 10kHz oscillator provides timing for the sniff, burst transmit and housekeeping
functions, respectively. This oscillator requires no external components. The 10kHz oscillator’s internal trim capacitor is trimmed by
eight bits of trim control via self-calibration. Once the trim is set, the oscillator frequency will be accurate to within two percent over
specified voltages and temperatures.
5.2 Receiver
The AMIS-53050 has a single channel receiver. The LNA for the receiver input requires a DC connection to ground on the input (must
not be an RF ground connection). The LNA for the receiver input requires a DC connection to RFVDD on the output. These connections
are supplied through inductors, L_rx and L_LNA, becoming part of the matching circuit for the receiver input.
