MLS9109-00881

Surface Mount Frequency Synthesizer

CDMA 869 -894 MHz

Features

• Integrated VCO/PLL

• Miniature SMT Package

• Low Phase Noise

• +5V Operation

Description

The MLS9109-00881 synthesizer design integrates a high perfor-

mance buffered VCO, PLL circuit and discrete loop filter in a

surface mount package. The SMT packaging provides electrical

shielding, easy PCB assembly and repeatable performance. The

synthesizer is designed for use in CDMA base stations and is

optimised for coverage of the cellular Tx band, 30 kHz step size

and low phase noise requirements.

M/A-COM synthesizers are manufactured in an ISO 9001 certi-

fied facility, incorporating surface mount assembly and automated

electrical testing. This ensures consistent electrical performance

and quality over volume production quantities.

1. All specification limits are indicated values and apply over FOUT and

for 50 Ω load impedance.

2. Programming control is 3 wire serial CMOS or TTL levels, in accor-

dance with National Semiconductor LMX 1511.

3. Output power window includes variation over operating temperature

range (TOP) -40°C to +85°C and output frequency range (FOUT).

4. See plot for typical phase noise at other frequency offsets.

5. See plot for typical full band switching time measured to within

other offsets from final frequency.

6. Integral PLL lock monitor output, TTL high locked, TTL low un-

locked.

7. Device designed for loop bandwidth of 150 Hz.

8. Reference frequency input impedance 10 kΩ min.
