FEATURES
DESCRIPTION
The DS76KHz is a temperature-compensated crystal oscillator (TCXO) with an output frequency of 76.8
kHz.
DS76KHz-N respectively.
The DS76KHz requires four pins for operation: V
3 for connection schemes. Power is applied via V
output in the absence of power. The output is accurate to 7.5 ppm from -40 C to +85 C and 2 ppm
from 0°C to 40°C.
The DS76KHz is packaged in a small 36-pin SMD, utilizing Ball Grid Array (BGA) technology, with
dimensions 0.400 inches wide, 0.450 inches long, and 0.180 inches high.
The recommended land pattern layout is shown on page 5.
The additional board space required is negligible in most applications and therefore the recommended
land pattern layout should be implemented on all new designs and future board revisions to satisfy
applications requiring better accuracy.
