Manufacturer:MURATA Description:ble divider divides by (N a 1) N being the number loaded into the shift register (bits 1 C 13 after address) It is clocked by the AM input via an ECL d prescaler or through a dprescaler from the FM input The AM input will work at frequencies up to 15 MHz while the FM input works up to 120 MHz The AM band is tuned with a frequency resolution of 10 kHz and the FM band is tuned with a resolution of 25 kHz The buffered AM and FM inputs are self biased and can be driven directly by the VCO through a capacitor The ECL phase comparator produces very accurate resolution of the phase difference between the input signal and the reference oscillator The high speed charge pump consists of a switchable constant current source (b0 3 mA) and a switchable constant current sink ( a 0 3 mA) If the VCO fre- quency is low the charge pump will source current and sink current if the VCO frequency is high When using an AFC the charge pump output may be forced into TRI-STATE by applying a low level to the charge pump enable input A separate VCCM pin (typically drawing 1 5 mA) powers the oscillator and reference chain to provide controller clocking frequencies when the balance of the PLL is powered down |
