| UT7R995 | 5962-05124 | QML-Q, QML-V | ≤109 | 100 | 8 | 6MHz to 200MHz | +2.25V to +3.6V | 48-lead FP |
The UT7R995 is a low-voltage, low power, eight output, 6-to-200MHz clock driver.
The device features output phase programmability, which is necessary to optimize the timing of high-performance microprocessor and communication systems. The device also feature split output bank power supplies that enable banks 1 & 2, bank 3, and bank 4 to operate at a different power supply levels. The UT7R995 interfaces to a LVCMOS/LVTTL clock only.
