September 1995 Edition 6.0a DATA SHEET MB1501/MB1501H/MB1501L SERIAL INPUT PLL FREQUENCY SYNTHESIZER SERIAL INPUT PLL FREQUENCY SYNTHESIZER WITH 1.1GHz PRESCALER The Fujitsu MB1501/MB1501H/MB1501L, utilizing BI-CMOS technology, is a single chip serial input PLL frequency synthesizer with pulse-swallow function. The MB1501 series contain a 1.1GHz two modulus prescaler that can select either 64/65 or 128/129 divide ratio; control signal generator; 16-bit shift register; 15-bit latch; programmable reference divider (binary 14-bit programmable reference counter); 1-bit switch counter; phase comparator with phase inverse function; charge pump; crystal oscillator; 19-bit shift register; 18-bit latch; programmable divider (binary 7-bit swallow counter and binary 11-bit programmable counter). The MB1501 operates on a low supply voltage (3V typ) and consumes low power (45mW at 1.1GHz).

However, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional operation should be restricted to the conditions as detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Oscillator output. A crystal is placed between OSCIN and OSCOUT. Power supply input for charge pump. Power supply voltage input. Charge pump output. Phase characteristic can be inversed depending upon FC input. Ground. Phase comparator output. This pin outputs high when the phase is locked. While the phase difference of fr and fp exists, the output level goes low. Prescaler input. The connection with an external VCO should be an AC connection. Clock input for 19-bit shift register and 16-bit shift register. Each rising edge of the clock shifts one bit of data into the shift registers. Serial data of binary code input. The last bit of the data is a control bit. The last data bit specifies which latch is activated. When the last bit is high level and LE is high-level, data is transferred to 15-bit latch. When the last bit is low level and LE is high level, data is transferred to 18-bit latch. Load enable input (with internal pull up resistor). When LE is high level (or open), data stored in the shift register is transferred to latch depending on the control data. Phase selecting input of phase comparator (with internal pull up resistor). When FC is .
