LC72725KV开发板套件编程器的射频评估开发套件开发板规格书PDF中文资料

LC72725KV属于开发板套件编程器的射频评估开发套件开发板。由安森美半导体公司制造生产的LC72725KV射频评估和开发套件，开发板本系列中的产品适用于在已知实施环境中，提供能访问射频相关器件的功能或者有助于访问该功能。所含的焦点产品范围从射频信号链元器件（如放大器和检测器）到模块化收发器，以及不直接包含焦点产品的适配器硬件，但此类硬件可供方便地访问用户单独提供的特定射频产品或系列。

Overview

The LC72725KM and LC72725KV are ICs that implement the signal processing required by the European Broadcasting Union RDS (Radio Data System) standard and by the US NRSC (National Radio System Committee) RBDS (Radio Broadcast Data System) standard. These ICs include band-pass filter, demodulator,and data buffer RAM on chip. RDS data can be read out from this on-chip memory by external clock input in slave operation mode.

Functions

• Bandpass filter: Switched capacitor filter (SCF)

• RDS Demodulation: 57KHz carrier and RDS data clock regeneration, biphase decode, differential decode.

• Buffer RAM: 128 bit (about 100ms) can be restored in the on-chip data buffer RAM.

• Data output: Master or slave output mode can be selected.

• RDS-ID: Detect RDS signal which can be reset by RST signal input.

• Standby control: Crystal oscillator can be stopped.

• Fully adjustment free

• Low Voltage
