MLS9208-01800
Surface Mount Frequency Synthesizer
CDMA 1770 - 1832 MHz
Features
• Integrated VCO/PLL
• Miniature SMT Package
• Low Phase Noise
• +5V Operation
Description
The MLS9208-01800 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 PCS CDMA base stations and is
optimised for 50 kHz step size and low phase noise and spurious
performance.
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 50Ω load impedance.
2. Programming control is 3 wire serial CMOS or TTL levels, in accor-
dance with National Semiconductor LMX 2325.
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 300 Hz.
8. Reference frequency input impedance 10 kΩ min.
