IMI4350 PHASE DETECTOR May 1998 Approved Product CMOS LSI PLL FREQUENCY SYNTHESIZERS PRODUCT DESCRIPTION PRODUCT FEATURES The IMI4350 is a member of a family of phaselock loop synthesizer ICs from International Microcircuits. This is a phase-frequency detector intended for use with high reference frequencies. Compatible with sinewave, ECL, TTL, and CMOS input waveforms makes the IMI4350 extremely versatile in wideband PLL applications. æ æ æ æ æ æ >40 MHz typical input frequency Low power consumption CMOS -163 dBc/Hz total phase noise floor No dead zone, by design Lock detect output Polarity switch to invert PDout polarity for active filtering The IMI4350 is a Type IV phase frequency detector which has eliminated by design the inherent dead zone which causes crossover distortion at the critical center lock point. The IMI circuitry enables consistent low noise loop designs using the simple single ended charge pump output. Lock detect output is also provided. æ æ æ æ æ æ æ æ æ 380 µA Current Mode Charge Pump Unambiguous PLL acquisition Zero degree phase difference at lock ECL compatible inputs when AC coupled Sinewave inputs when AC coupled TTL, CMOS inputs can be DC coupled On- or off-chip reference oscillator operation Small 8 pin SOP package for SMT available 3-volt and 5-volt characterizations BLOCK DIAGRAM VDD POL 3 8 8 OSCout PFD 2 25 OSCin Fin VSS 1 6 1 2 1 1 2 1 7 5 PDout LD 2 2 4 INTERNATIONAL MICROCIRCUITS, INC. 525 LOS COCHES ST.

For proper operation, Vin Ambient Temperature: -40º C to 85º C and Vout should be constrained to the range: Recommended Operating Range: 4.5-5.5V Vss<(Vin or Vout)<VDD Unused inputs must always be tied to an appropriate logic voltage level (either VSS or VDD). PIN NO. PIN DESCRIPTIONS DESCRIPTION NAME 1 OSCin This input is self biased and is designed to be AC coupled for low level sinewave signals. 2 OSCout Reference signal output can be used in conjunction with OSCin to form an internal crystal oscillator. 6 Fin This input is intended to be AC coupled for low level sinewave signals. DC coupling can be 4 VSS Circuit ground. 8 VDD Circuit positive power supply. 3 POL Polarity swtich default is low (internal pull down). 5 LD Loct detect output. This signal goes LOW when the loop is out of lock. 7 Pdout Single-ended charge pump output, usually used with passive loop filters. This signal used for CMOS logic level input signals. operates according to the following: If POL = 0 Can be used with inverting If POL = 1 æ æ æ Frequency fv>fr at the phase detector: negative pulses. Frequency fv<fr at the phase detector: positive pulses. Frequency fv = fr at the phase detector: high-impedance state. Frequency fv>fr at the phase detector: positive pulses.
