LTC1264-7

Linear Phase, Group Delay

Equalized, 8th Order

Lowpass Filter

DESCRIPTIO

■

Steeper Roll-Off Than Bessel Filters

High Speed: f_C≤ 200kHz

Phase Equalized Filter in a 14-Pin Package

Phase and Group Delay Response Fully Tested

Transient Response Exhibits 5% Overshoot and

No Ringing

The LTC1264-7 is a clock-tunable monolithic 8th order

lowpass filter with linear passband phase and flat group

delay. The amplitude response approximates a maximally

flat passband and exhibits steeper roll-off than an equiva-

lent 8th order Bessel filter. For instance, at twice the cutoff

frequency the filter attains 28dB attenuation (vs 12dB for

Bessel), while at three times the cutoff frequency the filter

attains 55dB attenuation (vs 30dB for Bessel). The cutoff

The clock-to-cutoff frequency ratio of the LTC1264-7 can

be set to 25:1 (pin 10 to V⁺) or 50:1 (pin 10 to V^–).

Data Communication Filters

Time Delay Networks

Phase Matched Filters

When the filter operates at clock-to-cutoff frequency ratio

of 25:1, the input is double-sampled to lower the risk of

aliasing.

The LTC1264-7 is optimized for speed. Depending on the

operating conditions, cutoff frequencies between 200kHz

and250kHzcanbeobtained.(PleaserefertothePassband

vs Clock Frequency graphs.)

The LTC1264-7 is pin-compatible with the LTC1064-X

series.
