SP8714
2100 MHz Very Low Current Multi-Modulus Divider
March 2006
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 is
designed to interface with CMOS synthesisers.
