The device is capable of providing 10-channel receiver. 6.1 Mixer and Limiter The mixer-oscillator (VCO) combination converts the input frequency (e.g., 27MHz) down to 455KHz, where, after external bandpass filtering, most of the amplification is done. The audio is recovered using a conventional quadrature FM detector. After suitable bandpass filtering (ceramic or LC), the signal goes to the input of limiter amplifier at Pin 8. The output of the limiter at Pin 11 drives a multiplier to detect the FM. This is accomplished both internally (direct access), and externally through a quadrature coil or discriminator. The other side of the limiter stages is decoupled at Pins 9 and 10. The limiter IF amplifier typically has about 75dB of gain. Decoupling capacitors should be placed close to the decoupling Pins 9 and 10 to ensure low noise and stable operation. A simple inverter OP amp is provided with an output at Pin 15 providing DC bias to be input at Pin 14, and positive input at Pin 17 for reference voltage set. The filter can be made with external impedance elements to discriminate between frequencies. 6.2 VCO The circuit employed an LC-tank structure to achieve low-phase noise characteristic where “L” is an off-chip high-Q inductor, and “C” is provided by a varactor with different tuning ranges. 6.3 PLL The PLL includes 64/65 prescaler, charge pump, PFD, N-A swallow counters, and R-counter for the multi-channel applications. The channels are selected for ESW5211 via mechanical switches of parallel BCD input. For ESW5210, the channels can be easily set by an input pin CHCLK which directly selects the ROM table addresses.

The initial or default channel at power on (internal power on reset) is set at Channel 10. 6.4.2 ESW5211 The input provides BCD code for selecting one of ten channels to be locked in both transmit and receive loop. When address data other than 1 – 10 are input, the decoding logic defaults to channel 10. shown in the table below. The frequency assignments with D0 – D3 are The D0 – D3 inputs have internal pull up devices. VCO Frequency and Divider Ratio Oscillator Frequency 4.0MHz, Ref.
