ASK
ASK/FSK Receiver Uses a Low IF Architecture with High Selectivity,
Blocking and Low Intermodulation (Typical 3 dB Blocking
55.5 dBC at ±750 kHz/60.5 dBC at ±1.5 MHz and 67 dBC at ±10 MHz,
System I1dBCP = –30 dBm/System IIP3 = –20 dBm)
Wide Bandwidth AGC to Handle Large Outband Blockers above the System I1dBCP
226 kHz IF (Intermediate Frequency) with 30 dB Image Rejection and 220 kHz System
Bandwidth to Support TPM Transmitters using ATA5756/ATA5757 Transmitters with
Standard Crystals
