specification limits.
(2) Measurement made using a PSKEY_LC_MAX_TX_POWER setting corresponds to a
PSKEY_LC_POWER_TABLE power table entry of 63.
(3) Class 2 RF transmit power range, Bluetooth v2.1 + EDR specification.
(4) To some extent these parameters are dependent on the matching circuit used, and its behaviour
over temperature. Therefore these parameters may be beyond CSR’s direct control.
(5) Resolution guaranteed over the range -5dB to -25dB relative to maximum power for Tx Level
>20.
(6) Measured at F0= 2441MHz.
(7) Up to three exceptions are allowed in the Bluetooth v2.1 + EDR specification. BlueCore4 is
guaranteed to meet the ACP performance as specified by the Bluetooth v2.1 + EDR specification.

Notes:
(1) Up to five exceptions are allowed in the Bluetooth v2.1 + EDR specification. BlueCore4 is
guaranteed to meet the C/I performance as specified by the Bluetooth v2.1 + EDR specification.
(2) Measured at F0 = 2441MHz
(3) Measured at f1-f2 = 5MHz. Measurement is performed in accordance with Bluetooth RF test
RCV/CA/05/c. i.e. wanted signal at -64dBm
(4) Measured at the unbalanced port of the balun. Integrated in 100kHz bandwidth and then
normalized to 1Hz. Actual figure is typically below TBD dBm/Hz except for peaks of -52dBm
