9161A-01CW16LFT General Description

The 9161A-01 is a fully programmable graphics clock generator. It can generate user-specified clock frequencies using an externally generated input reference or a single crystal. The output frequency is programmed by entering a 24-bit digital word through the serial port. Two fully user-programmable phaselocked loops are offered in a single package. One PLL is designed to drive the memory clock, while the second drives the video clock. The outputs may be changed on-the-fly to any desired frequency between 390 kHz and 120 MHz.

The 9161A-01 is ideally suited for any design where multiple or varying frequencies are required. This part is ideal for graphics applications. It generates low jitter, high speed pixel clocks. It can be used to replace multiple, expensive high speed crystal oscillators. The flexibility of the device allows it to generate non-standard graphics clocks.

The 9161A-01 is also ideal in disk drives. It can generate zone clocks for constant density recording schemes. The low profile, 16-pin SOIC or PDIP package and low jitter outputs are especially attractive in board space critical disk drives.
