M8R Series 3.3 Volt HCMOS/TTL Compatible
Ceramic Package Surface Mount Oscillators
These are non-PLL based high frequency
oscillators (80.001 - 125.000 MHz), intended for
applications that require low phase jitter. Features
grounded lid for reduced EMI. This product is
available in both 5.0 V (M7R) and 3.3 V (M8R).
For frequencies 80.000 MHz and below, please
see the M8S series.

Electrical Specifications
Pin Connections
Tri-state Control Logic
Pin 1 high or floating: clock signal output.
Pin 1 low: output disabled to high
impedance.
TTL load - See load circuit diagram #1 on page 137. HCMOS load - See load circuit diagram #2 on page 137.
Symmetry is measured at 1.4 V with TTL load and at 50% Vdd with HCMOS load.

Rise/Fall times are measured between 0.5 V and 2.4 V with TTL load, and between 10% Vdd and 90% Vdd with HCMOS load.
See page 136, Figure 2 for suggested solder profile.
