Features
Applications
• Operating voltage 2.7V to 5.5V
• Operating frequency to 1.2 GHz and 600 MHz with in-
puts of –15 dBm and VCC of 3.0V
The Cypress CYW2332 is a dual serial input PLL frequency
synthesizer designed to combine the RF and IF mixer frequen-
cy sections of wireless communications systems. One 1.2-
GHz and one 600-MHz prescaler, each with pulse swallow ca-
pability are included. The device operates from 2.7V and dis-
sipates only 15 mW.
• Lock detect feature
µA typical at 3.0V
• Power-down mode ICC < 1
• Available in a 20-pin TSSOP (Thin Shrink Small Outline
Package)
• Available in a 24-pin CSP (Chip Scale Package)
• Available in a 20-pin MLF (Mirco Lead Frame Package)

Handling Precautions
Devices should be transported and stored in antistatic con-
tainers.
Protect leads with a conductive sheet when handling or trans-
porting PC boards with devices.
These devices are static sensitive. Ensure that equipment and
personnel contacting the devices are properly grounded.
If devices are removed from the moisture protective bags for
more than 36 hours, they should be baked at 85°C in a mois-
ture free environment for 24 hours prior to assembly in less
than 24 hours.
Cover workbenches with grounded conductive mats.

Function
Control Bits: Directs programming data to PLL1 (high frequency) or PLL2 (low frequency).
Reference Counter Setting Bits: 15 bits, R = 3 to 32767.[7]
Phase Sense of the Phase Detector: Set to match the VCO polarity, H = + (Positive VCO transfer function).
Charge Pump Setting Bit: IDO HIGH = 3.8 mA, IDO LOW = 1 mA at VP = 3V.
Hi-Impedance State Bit: Makes DO Hi-Impedance for PLL1 and PLL2 when HIGH.
IDO

LD
Lock Detect: Directs the lock detect signal source pin 10. Pin 10 is HIGH with narrow low excursions when
locked. When not locked, this pin is LOW.
FO
Frequency Out: This bit can be set to read out reference or programmable divider at the LD pin for test
purposes.
PRE
PD
Prescaler Divide Bit: For PLL1: LOW = 64/65 and HIGH = 128/129. For PLL2: LOW = 8/9 and HIGH = 16/17.
Power-down: LOW = power-up and HIGH = power-down. FIN is at a high-impedance state, respective B
counter is disabled, forces DO outputs to Hi-Impedance and phase comparators are disabled. The reference
counter is disabled and the OSC input is high-impedance after both PLLs are powered down. Data can be
input and latched in the power-down state.
A1–A7
Swallow Counter Divide Ratio: A = 0 to 127 for PLL1 and 0 to 15 for PLL2.
Programmable Counter Divide Ratio: B = 3 to 2047.[7]

Notes:
8. B is greater than or equal to A.
9. Divide ratio less than 3 is prohibited. The divide ratio can be calculated using the following equation:
fvco = {(P * B) + A} * fosc / R where (A < B)
fvco: Output frequency of the external VCO.
fosc: The crystal reference oscillator frequency.
A: Preset divide ratio of the 7-bit swallow counter (0 to 127) and the 4-bit swallow counter (0 to 15).
B: Preset ratio of the 11-bit programmable counter (3 to 2047).
P: Preset divide ratio of the dual modulus prescaler.
R: Preset ratio of the 15-bit programmable reference counter (3 to 32767).
The divide ratio N = (P * B) + A.
10. Operating temperature range: –40°C to +85°C.
