4 / 11 page MC2800SYNEVK 4 MOTOROLA RF/IF DEVICE DATA ELECTRICAL CHARACTERISTICS (continued) Characteristic Unit Max Typ Min Symbol Conditions LNA + SAW FILTER + MIXER Conversion Gain [Note 2] Input @ 282.000 MHz GC – 28.2 – dB Output @ 21.400 MHz Zout @ 21.400 MHz Zout – 1620 – j51 – Ω Current Consumption of Mixer Vreg = 0.980 V I – 370 – µA CRYSTAL FILTER Insertion Loss Terminating Impedance = 1.5 k Ω – 1.0 – dB IF RECEIVER MC2800 Input Impedance @ 21.400 MHz Zin – 1090 – j140 – Ω Second Local Oscillator Frequency fLO2 – 20.95008 – MHz Startup Time of 2nd LO EN transits from ’0’ to ’1’ – <1.0 – ms Current Consumption VCC = 1.15 V – 1.45 – mA OVERALL RECEIVER PERFORMANCE (a) Phase A Characteristics [Note 3] RF Input Frequency N – Counter = 28B8(H) – 282.000 – MHz Sensitivity 6400/4 Level FSK R1 = ’0’ – –123 – dBm 1600/2 Level FSK R1 = ’1’ – –123 – dBm Co–channel Rejection – –5.0 – dB Adjacent Channel Rejection dB Low Side – 56 – High Side – 59 – Image Rejection dB First IF 6400/4 Level FSK – 56 – Second IF 6400/4 Level FSK R1 =’0’ – 51 – Intermodulation Rejection R1 = 0 dB Low Side – 52 – High Side – 52 – Blocking dB @ 1.0 MHz – 73 – @ 5.0 MHz – 78 – Total Current Consumption Power Up @ VCC = 1.15 V – 4.3 – mA Power Down @ VCC = 1.15 V – 10 – µA NOTES: 1. Output of the LNA is matched to 230 Ω by inserting a 180 Ω resistor in series with its output port. 2. Output of the Mixer is matched to 1.5050 k Ω by inserting a 1500 Ω resistor in series with its output port. 3. The circuit of this test board is the same as the schematic in Figure 2.
