SP8714
2100 MHz Very Low Current Multi-Modulus Divider
October 2005
The SP8714 is a switchable divide by 32/33, 64/65
Ordering Information
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.

2. All electrical testing is performed at +85°C.
3. Typical values are measured at +25°C and VCC = +5V.
4. Modulus Control and Ratio Select are high impedance inputs which can be driven directly by standard CMOS outputs.
5. Modulus control is latched at the end of the previous cycle.
6. See Figure 4.
7. See Figure 8.
8. These parameters are not tested but are guaranteed by design.
9. The ratio select pin is not intended to be switched dynamically.

OPERATING NOTES
The RF inputs are biased internally and are normally coupled to the signal source with suitable capaitors.
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/µs.
POWER DOWN (pin 7) is connected internally to a pull-up resistor. If the battery economy facility is not used, pin 7 should
be connected to VEE
