Wide Band FSK Receiver
CXA3067M
Description
The CXA3067M is an integrated circuit designed
for CATV wide band FSK receiver. This monolithic
IC is composed of local oscillator, double balanced
mixer, limiter, FM detector, data shaper and PLL
circuit in a single chip.
30 pin SOP (Plastic)
Features
• Built in PLL
• 3 bits 3 states frequency selection
• Applied for 4 reference frequency
(7.15625/7.15909/14.3125/14.31818 MHz)
• Compatible with external reference clock and X’tal
oscillator
• Balanced oscillator and double balanced mixer for
low L.O. leakage
• Low power consumption
• SOP 30 pin package
