Maximum ratings are absolute ratings; exceeding only one of these values may cause irreversible damage to the
integrated circuit.

The listed characteristics are ensured over the operating range of the integrated circuit. Typical characteristics
specify mean values expected over the production spread. If not otherwise specified, typical characteristics apply
at TA = 25 °C and the given supply voltage.

Bipolar IC
)XQFWLRQDOꢀ'HVFULSWLRQꢅꢀ$SSOLFDWLRQ
The IC is designed for use in mobile radio communication
devices up to 2100 MHz and upconversion systems up 2500
MHz.
Due to its low power consumption and low phase noise
generation it is suitable for the use in battery powered handheld
systems, e.g. PCN, DECTand wireless LANs.
Low supply voltage down to 2.7V.
It can be switched to a low-power standby mode.
Internal current source at the emitter follower output. No external resistor needed in typical
applications.
The divide ratio is 1:64/65 or 1:128/129 depending on the external circuit configuration.

&LUFXLWꢀ'HVFULSWLRQ
The differential inputs of the IC may be connected either balanced or single ended. In the latter case
the unused input must be RF-grounded with a capacitor (about 10 pF) with a low serial inductance.
Depending on the logic level at SW input the basic divide ratio of the ECL-stages is fixed to 1:64/65
or 1:128/129. The MOD input determines whether modulus 1:n or 1:n+1 (n=64 or 128 according to
SW-level) is active.
The IC can be switched to a low-power standby mode (input STB).
The MOD input is TTL/CMOS compatible.
The emitter follower output is CMOS compatible according to the application circuit on page 11. The
minimum logic swing is 0.8 Vpp.
