STLC2150
GENERAL SPECIFICATION
All the provided values are specified over the operational conditions (VDD and temperature) according to the
Bluetooth® v.1.2 specification.
Receiver
To comply with the Bluetooth® norm, an external RF filter is required to provide minimum 17dB of attenuation
in the bands: 30MHz - 2000MHz and 3000MHz - 12.75GHz. All specification below are measured at the antenna
port. The loss between IC inputs and the port is approximately 2dB

The RSSI value is stored in the RSSI register. The value is latched when the base-band sends the access code
recognition signal (BPKTCTL) and is kept unchanged until the next RX active slot. The register can be read by
the base-band at any time
