ML12210
Serial Input PLL
Frequency Synthesizer
Legacy Device: Motorola MC12210
The ML12210 is a 2.5 GHz Bipolar monolithic serial input
phase locked loop (PLL) synthesizer with pulse–swallow function.
It is designed to provide the high frequency local oscillator signal
of an RF transceiver in handheld communication applications.
The technology used allows for low power operation at a mini-
mum supply voltage of 2.7 V. The device is designed for operation
over 2.7 to 5.5 V supply range for input frequencies up to 2.5 GHz
with a typical current drain of 9.5 mA. The low power consump-
tion makes the ML12210 ideal for handheld battery operated
applications such as cellular or cordless telephones, wireless LAN
or personal communication services. A dual modulus prescaler is
integrated to provide either a 32/33 or 64/65 divide ratio.
• Low Power Supply Current of 8.8 mA Typical for ICC
and 0.7 mA Typical for Ip
• Supply Voltage of 2.7 to 5.5 V
• Dual Modulus Prescaler With Selectable Divide Ratios
of 32/33 or 64/65
• On–Chip Reference Oscillator/Buffer
• Programmable Reference Divider Consisting of a
Binary 14–Bit Programmable Reference Counter
• Programmable Divider Consisting of a Binary 7–Bit
Swallow Counter and an 11–Bit Programmable Counter
• Phase/Frequency Detector With Phase Conversion Function
• Balanced Charge Pump Outputs
• Dual Internal Charge Pumps for Bypassing the First
Stage of the Loop Filter to Decrease Lock Time
• Outputs for External Charge Pump
• Operating Temperature Range of TA = –40 to 85°C
NOTE: Also available is the ML12202, a 1.1 GHz version of this
function.
