LTC1569-6 - Linear Phase, DC Accurate, Low Power, 10th Order Lowpass Filter - Linear Technology（凌力尔特）
功能描述
The LTC1569-6 is a 10th order lowpass filter featuring linear phase and a root raised cosine amplitude response. The high selectivity of the LTC1569-6 combined with its linear phase in the passband makes it suitable for filtering both in data communications and data acquisition systems.
Furthermore, its root raised cosine response offers the optimum pulse shaping for PAM data communications. The filter attenuation is 50dB at 1.5 • fCUTOFF, 60dB at 2 • fCUTOFF, and in excess of 80dB at 6 • fCUTOFF. DC-accuracy-sensitive applications benefit from the 5mV maximum DC offset.
The LTC1569-6 sampled data filter does not require an external clock yet its cutoff frequency can be set with a single external resistor with a typical accuracy of 3.5% or better. The external resistor programs an internal oscillator whose frequency is divided by either 1, 4 or 16 prior to being applied to the filter network. Pin 5 determines the divider setting. Thus, up to three cutoff frequencies can be obtained for each external resistor value. Using various resistor values and divider settings, the cutoff frequency can be programmed over a range of six octaves. Alternatively, the cutoff frequency can be set with an external clock and the clock-to-cutoff frequency ratio is 64:1. The ratio of the internal sampling rate to the filter cutoff frequency is 128:1.
The LTC1569-6 is fully tested for a cutoff frequency of 64kHz with a single 3V supply.
The LTC1569-6 features power saving modes and it is available in an SO-8 surface mount package.
