8 / 34 page Philips Semiconductors Product data SA2400A Single chip transceiver for 2.45 GHz ISM band 2002 Nov 04 8 7. OPERATING CONDITIONS Table 3. Absolute Maximum Ratings Symbol Parameter Min Max Unit Tstg Storage temperature –55 +150 °C VDD Supply voltage –0.5 +3.85 V Voltage applied to inputs –0.5 VDD+0.5 V Short circuit duration, to GND or VDD – 1 second Table 4. Recommended Operating Conditions Symbol Parameter Min Nom Max Units Tamb Ambient operating temperature (Note 1) –30 – +85 °C VDD Supply voltage 2.85 3.3 3.6 V NOTE: 1. When the digital input mode is used, the lower limit of the ambient operating temperature is higher than –30 °C. Preliminary characterization results suggest a limit of –20 °C. This does not apply if the analog input mode is used. 8. OPERATIONAL MODES AND CURRENT CONSUMPTION (See also Table 18). Table 5. Operational modes and current consumption Tamb = 25 °C; VCC = 3.3 V. Main mode Duration Current (mA) Chip state Main mode (register 0x04) Other conditions Description Duration (max.) Min Typ Max POWER-UP SLEEP XO on, clock output on n/a 1.8 2.2 2.7 SLEEP SLEEP XO off Note 1. n/a – – 0.05 TX HI TX/RX or FASTTXRXMGC TXRX = HIGH; TX_HI = HIGH Synthesizer ON. Transmitter ON with 8 dBm driver. Maximum gain. n/a 120 143 170 TX LO TX/RX or FASTTXRXMGC TXRX = HIGH; TX_HI = LOW Synthesizer ON. Transmitter ON with –1.5 dBm driver. Maximum gain. n/a 81 95 105 RX TX/RX or RXMGC or FASTTXRXMGC TXRX = LOW Synthesizer ON. Receiver ON. Receiver gain control by: • TX/RX ⇒ internal AGC • RXMGC ⇒ 3-wire bus programming • FASTTXRXMGC ⇒ fast 3-wire bus n/a 81 95 105 WAIT WAIT Only Synthesizer and Xtal oscillator ON n/a 27 31 34 FCALIB FCALIB Calibrates cut-off frequency of Tx and Rx filters internally. Automatic transition to SLEEP mode upon completion. 3 µs – n/a – DCALIB DCALIB Maintain TX mode for 5 µs before calibration. Quiescent IQ input. Analog mode used. Calibration to reduce transmitter carrier leakage. Automatic transition to SLEEP mode upon completion. 20 µs – n/a – VCOCALIB VCOCALIB Calibrates internal VCO. 2200 µs – n/a – RESET RESET Resets IC into power-up state (SLEEP mode and all registers at default values) n/a – n/a – NOTE: 1. All digital inputs connected to GND or VDD. |
