DESCRIPTION
The M64811AGP is a 1.1GHz/500MHz band two-system one-chip PLL frequency synthesizer.
Using a high performance Bi-CMOS process , the product contains one two-modulus (1/32 and 1/33) prescaler that accepts inputs up to 1.1GHz and another two-modulus (1/16 and 1/17) prescaler that accepts inputs up to 500MHz ,thus helping make the equipment compact.

FEATURES
• Operating supply voltage : 2.7V~3.6V
• Operating temperature : -30°C~+85°C
• 2 PLL systems (1.1GHz and 500MHz) are on one chip .
   PLL1 : 700MHz~1.1GHz PLL2 : 100MHz~500MHz
• Low power consumption (Icc=8mA Typ at Vcc=3V) .
• Dividing ratio setting ranges :
   FIN1 for 1.1GHz VCO• • • • • N(VCO1)=1,024~131,071
   FIN2 for 500MHz VCO• • • • • N(VCO2)=256~131,071
   OSC for Fref • • • • • • • • • • • • • N(Fref)=5~2,047
• Each loop has input pin for sleep mode .
   Power supplies to 2 loops can be independently turned ON/OFF .
   Also can be controlled by the serial data . (When SLEEP1 and SLEEP2 is "H" . )
• The PLL standard oscillation circuit can adopt a B-E Colpitts type oscillation circuit to from a stable
   oscillation circuit.
• Current controlled charge pump . (Icp=±2mA const.)
• Locked condition detecting output
   If a phase difference smaller than 3 times (∆t) of the OSC period continues for 15 periods or
   longer , the condition is judged as locked, and the LOCK terminal goes to "L" .
   (When , for example , fosc=19.2 MHz , ∆t=156 ns)
• PLL lock/unlock status indicate function .
   (Judged in the system turned on if the other system is turned off . )
• Small package (16pin SSOP, lead pitch : 0.65mm)

APPLICATION
• Digital cordless phone (CT2)
• Digital cellular phone (PDC)
