Description
The MLS9037-00110 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 115 MHz IF at the cellular Tx frequency with 20 kHz,
step size and low phase noise.
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.

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
unlocked.
7. Device designed for loop bandwidth of 150 Hz.
8. Reference frequency input impedance 10 k
min.
1. All specification limits are indicated values and apply over F
OUT
and
for 50
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 (T
) -40°C to +85°C and output frequency range (F
OUT
).
4. See plot for typical phase noise at other frequency offsets.
