27GHz Parallel Load Professional Synthesiser
These are the inputs to the 16-bit data bus. When pin 38 is high the data goes to the buffers for the A counter, M counter and phase detector gain. When pin 38 is low the data goes to the buffers for the reference counter and the phase detector state (see Table 4). Open circuit = 1 (high) on these pins. Data is transparent from pins to the selected buffers when pin 39 (STROBE) is high and frozen in buffers when pin 39 is low. Balanced inputs to the RF preamplifier. For single-ended operation the signal is AC-coupled into pin 13 with pin 14 AC-decoupled to ground (or vice-versa). Pins 13 and 14 are internally DC biased. A current sink into this pin is enabled when the lock detect circuit indi...

Mitel Networks
13GHz Professional Synthesiser
Prescaler and AM Counter The programmable divider chain is of AM counter design and therefore contains a dual modulus front end prescaler, an A counter which controls the dual modulus ratio and an M counter which controls the bulk multi-modulus division. A programmable divider of this type has a division ratio of MN1A and a minimum integer steppable division ratio of N(N21). In the SP8853, the dual modulus front end prescaler is a dual N ratio device, capable of being statically switched between 416/17 and 48/9 ratios. The controlling A counter is of four-bit design, allowing a maximum count sequence of 15 (2421), which begins with the start of the M counter sequence and stops when it has co...
