Description

The DS76KHz is a temperature-compensated crystal oscillator (TCXO) with an output frequency of 76.8 kHz. This device is available in commercial and industrial temperature versions, DS76KHz and DS76KHz-N respectively.

The DS76KHz requires four pins for operation: VCC, GND, VBAT and 76KHz OUT. See Figures 1, 2 and 3 for connection schemes. Power is applied via VCC and GND, while VBAT is used to maintain the 76KHz 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.
