Applications
The QX8T50B12.00000B50TT provides a stable 12 MHz clock reference for legacy microcontroller systems, UART baud rate generation, and embedded digital logic requiring HCMOS-compatible timing. Its tri-state and enable/disable features allow multiple oscillators to share a clock bus or be power-gated in sleep modes, extending battery life in portable instruments. The through-hole DIP package is ideal for prototype boards, industrial control hardware, and legacy system maintenance where SMT rework capability is limited.

Frequently Asked Questions
How does the tri-state output feature of the QX8T50B12.00000B50TT benefit multi-oscillator clock bus designs?
The tri-state output allows the oscillator to disconnect its output from the clock bus by placing it in a high-impedance state, enabling multiple 12 MHz sources to share a single clock line without signal contention. Designs can switch between oscillators or disable unused ones to reduce current draw, which is useful in embedded systems that switch between normal and low-power sleep states.
Is ±50ppm frequency stability sufficient for UART communication at standard baud rates using the QX8T50B12.00000B50TT?
Yes, ±50ppm translates to a maximum frequency error of 600Hz at 12 MHz, which is well within the ±2% to ±3% tolerance required for reliable UART asynchronous communication at standard baud rates up to 115200 bps. The 12 MHz frequency also divides evenly to produce 9600, 19200, 57600, and 115200 bps with low baud rate error when used with standard UART dividers.
What PCB design considerations apply when using the 13.21mm × 13.21mm 8-pin DIP package of the QX8T50B12.00000B50TT?
The 8-pin DIP package with 13.21mm × 13.21mm footprint and 5.87mm height requires standard 2.54mm through-hole pad spacing with sufficient keepout clearance for the body on both sides of the board. The 10ns maximum rise and fall times and 50pF drive strength are compatible with direct connection to HCMOS inputs without external buffers, simplifying layout and reducing component count in prototype and low-volume industrial designs.
