SP8714

SP8714 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.
