LQ255T3LZ22K

The LQ255T3LZ22K is designed as one kind of low power, high performance frequency synthesizer system that can be used in (1)3G cellular base stations (WCDMA, TDSCDMA, CDMA2000); (2)2G cellular base stations (GSM/GPRS, EDGE, CDMA1xRTT); (3)wireless LAN; (4)broadband wireless access; (5)satellite communications; (6)wireless radio; (7)automotive; (8)CATV equipment; (9)instrumentation and test equipment; (10)RFID Readers. And this device is a monolithic integrated circuit, fabricated in an advanced BiCMOS process. So there are several different versions of this product in order to accomdate different frequency bands.

Features of the LQ255T3LZ22K are:(1)Fractional-N Delta Sigma Modulator Order programmable up to 4th order;(2)FastLock/Cycle Slip Reduction with Timeout Counter;(3)Partially integrated, adjustable Loop Filter;(4)Very low phase noise and spurs;(5)Integrated tank inductor;(6)Low phase noise;(7)2.8 V to 3.2 V Operation;(8)Low Power-Down Current;(9)1.8V MICROWIRE Support;(10)Package: 36 Lead LLP.

The absolute maximum ratings of the LQ255T3LZ22K can be summarized as:(1)Power Supply Voltage VCC: -0.3 V to 3.5 V;(2)Power Supply Voltage All other pins (Except Ground): -0.3 V to 3.0 V;(3)Storage Temperature Range: -65 °C to 150 °C;(4)Lead Temperature (solder 4 sec.): +260 °C.

The electrical characteristics of the LQ255T3LZ22K can be summarized as:(1)Oscillator Input High Current: 100 A;(2)Oscillator Input Low Current: -100 A;(3)Frequency Range: 5 to 80 MHz;(4)Oscillator Sensitivity: 0.5 to 2.0 Vpp;(5)Phase Detector Frequency: 32 MHz;(6)CP TRI-STATE Current: 2 to 10 nA;(7)Charge Pump Sink vs. Source Mismatch: 2 to 8 %.
