SP8714
2100MHz Very Low Current Multi-Modulus Divider
DS3562 - 5.0 July 1996
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.
