... The SP8714 is a switchable divide by 32/33, 64/65 programmable divider which is guaranteed to operate up to 2100MHz. It will operate from a supply of 2.7V to 5.25V and requires typically 6.8mA (including the output current). It also features a power down facility for battery economy. The RF inputs are internally biased and should be capacitively coupled to the signal source ...

... The output stage has a novel design and is intended to drive a CMOS synthesiser input. External pull-down resistors or circuits are not required. The SP8714 is not suitable for driving TTL or similar devices. The device will operate down to DC frequencies for non-sinusoidal signals provided that the input slew rate is better than 100V/µ ...
