PRELIMINARY HM6C5332 HM6C5332 – 1.2GHz/250MHz Dual Frequency Synthesizer Features        Description The HM6C5332 of full CMOS monolithic, dual frequency synthesizer is to be used as a local oscillator for RF and IF of a dual conversion transceiver. It is fabricated using Hyundai’s standard CMOS process. HM6C5332 contains dual modulus prescalers. A 64/65 or a 128/129 prescaler can be selected for RF synthesizer and a 8/9 or 16/17 prescaler can be selected for IF synthesizer. Using digital phase locked loop technique, HM6C5332 provides the tuning voltage for voltage controlled oscillators to generate very stable low noise RF & IF local oscillator signals. Serial data is transferred into the HM6C5332 via three wire interface (Data, Enable, Clock). Supply voltage can range from 2.7 to 3.6 V. HM6C5332 features very low current consumption; 3.2mA at 3.0V. HM6C5332 is available in a 20-pin TSSOP package and 24-pin LGA (Leadless Grid Array) package Applications      Functional Block Diagram             Portable Wireless Communications Cordless and Cellular Telephone Systems Wireless Local Area Networks(WLANs) Cable TV Tuners(CATV) Other Wireless Communication Systems     !   #$%   Full CMOS RF frequency synthesizer Low Current Consumption Selectable Powersave Mode Dual Modulus Prescaler Selectable Charge Pump High Z State 2.7V to 3.6V Operation Small Out Line 20 Pin TSSOP Package 24 Pin LGA(Leadless Grid Array) Package fIN IF     DO IF           DO RF       !"    fIN RF  PRELIMINARY Pin Assignment Leadless Grid Array Package Thin Shrink Small Outline Package ™ Pin Description Pin No. HM6C5332 24-pin LGA Package Pin No. HM6C5332 20-pin TSSOP Package PIN NAME I/O Description 24 1 VDDRF - Power supply voltage input for RF analog and RF digital circuits.

PRELIMINARY Functional Description The simplified block diagram below shows the 22-bit data register, two 15-bit R Counters and the 15-bit and 18-bit N Counters (intermediate latches are not shown). The data stream is clocked (on the rising edge of Clock) into the DATA input, MSB first. The last two bits are the Control Bits. The DATA is transferred into the counters as follows: CONTROL BITS C1 C2 0 0 0 1 1 0 1 1           DO IF DATA LOCATION IF R Counter RF R Counter IF N Counter RF N Counter fIN IF          !   #$%        !"         DO RF  fIN RF Programmable Reference Dividers (IF and RF R Counters) If the Control Bits are 00 or 01 (00 for IF and 01 for RF) data is transferred from the 22bit shift register into a latch which sets the 15-bit R Counter. Serial data format is shown below.                                                   15-Bit Programmable Reference Divider Ratio (R Counter) DIVIDE RATIO 3 4 • R 15 0 0 • R 14 0 0 • R 13 0 0 • R 12 0 0 • R 11 0 0 • R 10 0 0 • R 9 0 0 • R 8 0 0 • R 7 0 0 • R 6 0 0 • R 5 0 0 • R 4 0 0 • R 3 0 1 • R 2 1 0 • R 1 1 0 • 32767 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 NOTES: 1.

PRELIMINARY Programmable Divide (N Counter) The N counter consists of the 7-bit swallow counter (A counter) and the 11-bit programmable counter (B counter). If the Control Bits are 10 or 11 (10 for IF counter and 11 for RF counter) data is transferred from the 22-bit shift register into a 4bit or 7-bit latch (which sets the Swallow (A) Counter) and an 11-bit latch (which sets the 11-bit programmable (B) Counter), MSB first. Serial data format is shown below. For the IF N counter bits 5, 6, and 7 are don’t care bits. The RF N counter does not have don’t care bits.                                           !"#$!%  7-Bit Swallow Counter Divide Ratio (A Counter) RF DIVIDE RATIO A 0 1 • IF N 4 0 0 • N 7 0 0 • N 6 0 0 • N 5 0 0 • N 3 0 0 • N 2 0 0 • N 1 0 1 • DIVIDE RATIO A 0 1 • N 7 X X • N 6 X X • N 5 X X • N 4 0 0 • N 3 0 0 • N 2 0 0 • N 1 0 1 • 127 1 1 1 1 1 1 1 15 X X X 1 1 1 1 NOTES: 1.

The prescaler and powerdown modes are selected with bits N19 and N20. The programmable modes and truth table for the programmable modes are shown below. C1 0 0 1 1 C2 0 1 0 1 R16 IF Phase Detector Polarity RF Phase Detector Polarity R17 IF ICPO RF ICPO R18 IF DO High Z RF DO High Z R19 IF LD RF LD IF Prescaler RF Prescaler R20 IF FO RF FO Powerdown IF Powerdown RF Mode Select Truth Table PHASE DETECTOR POLARITY 0 1 Negative Positive DO High Z STATE Normal Operation High Z State ICPO (NOTE 1) LOW HIGH IF PRESCALER 8/9 16/17 RF PRESCALER 64/65 128/129 POWERDOWN (NOTE 2) Powered Up Powered Down NOTES: 1. Activation of the IF PLL or RF PLL powerdown modes result in the disabling of the respective N counter divider and debiasing of its respective fIN inputs (to a high impedance state). Powerdown forces the respective charge pump and phase comparator logic to a High Z State condition. The R counter functionality does not become disabled until both IF and RF powerdown bits are activated. The OSCIN pin reverts to a high impedance state when this condition exists. The control register remains active and capable of loading and latching in data during all the powerdown modes.

When the FO LD output is disabled, it is actively pulled to a low logic state. 2. Lock detect output provided to indicate when the VCO frequency is in “lock”. When the loop is locked and a lock detect mode is selected, the pins output is HIGH, with narrow pulse LOW. In the RF/IF lock detect mode a locked condition is indicated when RF and IF are both locked. 3. The Counter Reset mode bits R19 and R20 when activated reset all counters. Upon removal of the Reset bits then N counter resumes counting in “close” alignment with the R counter. (The maximum error is one prescaler cycle). If the Reset bits are activated the R counter is also forced to Reset, allowing smooth acquisition upon powering up.                                                                                                     PRELIMINARY Phase Detector Polarity Depending upon VCO characteristics, R16 bit should be set accordingly: When VCO characteristics are positive like (1), R16 should be set HIGH; When VCO characteristics are negative like (2), R16 should be set LOW.

Synchronously powerdown occurs if the respective loop’s R18 bit (Do High Z State) is LOW when its N20 bit (Powerdown) becomes HI. Asynchronous powerdown occurs if the loop’s R18 bit is HI when its N20 bit becomes HI. In the synchronous powerdown mode, the powerdown function is gated by the charge pump to prevent unwanted frequency jumps. Once the powerdown program bit N20 is loaded, the part will go into powerdown mode when the charge pump reaches a High Z condition. In the asynchronous powerdown mode, the device powers down immediately after the LE pin latches in a HI condition on the powerdown bit N20. Activation of either the IF or RF PLL powerdown conditions in either synchronous or asynchronous modes forces the respective loop’s R and N dividers to their load state condition and debiasing of its respective fin input to a high impedance state. The oscillator circuitry function does not become disabled until both IF and RF powerdown bits are activated. The control register remains active and capable of loading and latching data during all of the powerdown modes. The device returns to an actively powered up condition in either synchronous or asynchronous modes immediately upon LE latching LOW data into bit N20.
