the mc1452021 is pinforpin compatible with the previous generation mc145200, mc145201, and mc145202. table 1 highlights the different features in these four devices. the mc1452021 is recommended for new designs, and also offers improved suppression of reference sideband spurs. the counters are programmed via a synchronous serial port which is spi compatible. the serial port is byte-oriented to facilitate control via an mcu. due to the innovative bitgrabber plus ? registers, the mc1452021 may be cascaded with other peripherals featuring bitgrabber plus without requiring leading dummy bits or address bits in the serial data stream. in addition, bitgrabber plus peripherals may be cascaded with existing bitgrabber ? peripherals. the device features a singleended current source/sink phase detector a output and a doubleended phase detector b output. both phase detectors have linear transfer functions (no dead zones). the maximum current of the singleended phase detector output is determined by an external resistor tied from the rx pin to ground. this current can be varied via the serial port. slewrate control is provided by a special driver designed for the ref out pin. this minimizes interference caused by ref out . this part includes a differential rf input that may be operated in a singleended mode. also featured are onboard support of an external crystal and a programmable reference output. the r, a, and n counters are fully programmable. the c register (configuration register) allows the part to be configured to meet various applications. a patented feature allows the c register to shut off unused outputs, thereby minimizing system noise and interference. in order to have consistent lock times and prevent erroneous data from being loaded into the counters, onboard circuitry synchronizes the update of the a register if the a or n counters are loading. similarly, an update of the r register is synchronized if the r counter is loading. the doublebuffered r register allows new divide ratios to be presented to the three counters (r, a, and n) simultaneously. ? maximum operating frequency: 2000 mhz @ 10 dbm ? operating supply current: 4 ma nominal at 3.0 v ? operating supply voltage range (v dd , v cc , v pd pins): 2.7 to 5.5 v ? current source/sink phase detector output: 1.7 ma @ 5.0 v or 1.0 ma @ 3.0 v ? gain of current source/sink phase/frequency detector controllable via serial port ? r counter division range: 1 and 5 to 8191 ? dualmodulus capability provides total division up to 262,143 ? highspeed serial interface: 4 mbps ? output a pin, when configured as data out, permits cascading of devices ? two generalpurpose digital outputs: output a: totempole (pushpull) with four output modes output b: opendrain ? patented powersaving standby feature with orderly recovery for minimizing lock times, standby current: 30 m a ? see app note an1253/d for lowpass filter design, and an1277/d for offset reference plls for fine resolution or fast hopping bitgrabber and bitgrabber plus are trademarks of motorola, inc. this document contains information on a product under development. motorola reserves the right to change or discontinue this product without notice. ? motorola, inc. 1999 rev 0
