BCM2050

WLAN Chipset for 802.11a/b/g

Broadcom Corporation 

PLL Description

• Full Integration

• Integer-N PLL with programmable loop bandwidth

•

“Fractional-VCO†” with fvco = 2/3 frf

– Reduces pulling from high-power on-chip PA

– Reduces transmitter LO feed-through

– Reduces receiver DC offsets due to self-mixing

• Automatic frequency control integrated into PLL

• PLL achieves PN of < -100dBc/Hz@30KHz offset withfrf = 5.24 GHz
