... Mixer 2, limiter and demodulator In this 2. mixer stage the first 10.7 MHz IF is converted into the second 450 kHz IF. A multi- stage limiter generates signals for the complete integrated demodulator without external tank. MPX output DC offset versus noise DC level is correctable by software (DEM). ...

... The device gets an additional second IF narrow bandpass filter for suppression of noise and adjacent channel signal influences. This narrow filter has three switchable bandwidthes, narrow range of 80 kHz, mid range of 120 kHz and 30 kHz for weather band information. Without ISS filter the IF bandwidth (wide range) is defined only by ceramic filter chain. The filter is switched in after mixer 2 before 450 kHz limiter stage ...

... PLL frequency synthesizer block This part contains a frequency synthesizer and a loop filter for the radio tuning system. Only one VCO is required to build a complete PLL system for FM world tuning . For auto search stop operation an IF counter system is available. The counter works in a two stages configuration.

... This counter 21-bit synchronous autoreload down counter. Five bits (CF) are programmable to have the possibility for an adjust to the centre frequency of the IF-filter. The counter length is automatic adjusted to the chosen sampling time. At the start the counter will be loaded with a defined value which is an equivalent to the divider value (t Sample If a correct frequency is applied to the IF counter frequency input at the end of the sampling time the main counter is changing its state from 0h to 1FFFFFh ...

... SCL is HIGH will be interpreted as START or STOP condition. 4.6.2 Start condition A start condition is defined by a HIGH to LOW transition of the SDA line while SCL stable HIGH level. This "START" condition must precede any command and initiate a data transfer onto the bus. The device continuously monitors the SDA and SCL lines for a valid START and will not response to any command if this condition has not been met ...
