ML12202
MECL PLL Components Serial
Input PLL Frequency Synthesizer
Legacy Device: Motorola MC12202
The ML12202 is a 1.1 GHz Bipolar monolithic serial input
phase locked loop (PLL) synthesizer with pulse–swallow func-
tion. It is designed to provide the high frequency local oscillator
signal of an RF transceiver in handheld communication applica-
tions.
The technology is utilized allows for low power operation at a
minimum 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 1.1 GHz with a typical current drain of 6.5 mA. The low
power consumption makes the ML12202 ideal for handheld bat-
tery operated applications such as cellular or cordless tele-
phones, wireless LAN or personal communication services. A
dual modulus prescaler is integrated to provide either a 64/65 or
128/129 divide ratio.
• Low Power Supply Current of 5.8 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
64/65 or128/129
• 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 ML12210, a 2.5 GHz version of
this function.
Note: Lansdale lead free (Pb) product, as it
becomes available, will be identified by a part
number prefix change from ML to MLE.
