1.1 GHz PLL Frequency Synthesizer
MB15A01
s DESCRIPTION
The MB15A01 is a serial-input PLL (phase locked loop) frequency synthesizer LSI supporting a pulse swallow system.
The LSI consists of: a 1.1 GHz band, dual-modulus prescaler allowing either of 64/65 and 128/129 frequency divisions
to be selected, a control signal generator circuit, a 19-bit shift register, a 15-bit latch, a reference divider (binary 14-
bit reference counter), a 1-bit switch counter, a phase comparator with phase conversion functions, a charge pump,
a crystal oscillator, an 18-bit latch, and programmable dividers (binary 7-bit swallow counter and binary 11-bit pro-
grammable counter).
The LSI is housed in a 16-pin or 20-pin SSOP package, contributing to space saving of the system incorporating it.
In addition, the MB15A01 operates at a low supply voltage of 3.0 V (typical), achieving low current consumption
(typically ICC = 6.5 mA)
s FEATURES
• Operation at high speed:
• Pulse swallow function:
• Low current consumption:
fin = 1.1 GHz (Vin = –10 dBm)
Internal dual-modulus prescaler allowing either of 64/65 and 128/129 frequency
divisions to be selected
ICC = 6.5 mA (typical)

Precautions: Although the MB15A01 contains an antistatic element to prevent electrostatic breakdown and the
circuitry has been improved in electrostatic protection, observe the following precautions when
handling the device:
• When storing or carrying the device, put it in a conductive case.
• This is static-sensitive device; take proper anti-ESD Paricutin. Ensure that personnel and equip-
ment are properly grounded. Cover workbenches with grounded conductive mats.
• Before fitting the device into or removing it from the socket, turn the power supply off.
• Protect leads with conductive sheet when handling or transporting PC boards with devices.
