Description

TriQuint's TQ2059 is a high-frequency clock generator. It utilizes a 20 MHz to 35 MHz TTL input to generate a 200 MHz to 350 MHz PECL output. The TQ2059 has a completely self-contained Phase-Locked Loop (PLL) running at 400 MHz to 700 MHz. This stable PLL allows for a low period-to-period output jitter of 120 ps (max), and enables tight duty-cycle control of 55%to 45% (worst case).

The TQ2059 provides optional 200-ohm on-chip pull-down resistors which are useful if the output is AC-coupled to the device being driven. In order to use these resistors, pin 20 (PDR2) should be connected to pin 21 (QN), and pin 23 (PDR1) should be connected to pin 22 (Q).

Various test modes on the TQ2059 simplify debug and testing of systems by slowing the clock output or by bypassing the PLL.
