Description
The 281 field programmable spread spectrum clock synthesizer generates up to three high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input. It is designed to replace crystals, crystal oscillators and stand alone spread spectrum devices in most electronic systems. Using IDT's VersaClockTM software to configure PLLs and outputs, the 281 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include input/output frequencies, spread spectrum amount and eight selectable configuration registers. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost. The 281 is also available in factory programmed custom versions for high-volume applications.

SGAS701 footprint
In the datasheet for the sensor there is an outline drawing but no footprint information. Are there simply 4 pin in a square pattern at 5,08mm pitch (like the classic TO-39) or is it different? Also, figure 2 with the pin assigment is seen from above, right?
