from PIRA website: "This stereo encoder is a halfway between analogue and digital processing. It combines the best from both domains to provide high-quality and easy to build device. The sampling frequency used in this stereo encoder is 97 times (!!!) higher than the pilot tone frequency. This makes very easy to reject all spectral residues around the sampling frequency without affecting the main signal characteristics. Using of a microcontroller allows to build this stereo encoder with reduced part count and get excellent results in real operation." Characteristics: Signal overshooting prevention (overshooting max. 10 %) Low noise and distortion Pilot tone level, audio gain and output level adjustment High channel separation and spectral purity in common operation RDS input and pilot sync. output makes easy to connect any RDS encoder Microcomputer controlled Balanced audio input Supply voltage: 9-16 V (stabilized) Quiescent supply current (12 V): 34 mA Audio 19 kHz rejection: 40 dB Channel separation at 1 kHz: >55 dB Subcarrier rejection: >60 dB Pilot sampling frequency: 1.843 MHz (19 kHz x 97) Subcarrier sampling frequency: 1.843 MHz (38 kHz x 48.5) Pilot sync. output: TTL Max. audio input voltage: 10 V pp (3.55 V rms) Pilot tone level: linear adjustable 0-0.5 V pp Output voltage gain: linear adjustable 0-2.5 Audio input impedance: 600/10K ohm jumper selectable RDS input impedance: 1000 ohm MPX output impedance: 500 ohm Pilot sync. output impedance: 10000 ohm Signal-to-noise ratio: >70 dB Business Policy 1.
