SA121A datasheet

Description

The SA121A Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for bus connected systems. Supplying Pin 1 of the HA-1210 units with a logic “1″ enables the output on Pin 5. In the disabled mode, Pin 5 presents a high impedance to the load. All units are resistance welded in an all metal package, offering RFI shielding, and are designed to survive standard wave soldering operations without damage. Insulated standoffs to enhance board cleaning are standard.

Features

1. Wide frequency range – 0.5MHz to 36MHz
2. User specified tolerance available
3. Low Jitter
4. High Q Crystal actively tuned oscillator circuit
5. Power supply decoupling internal
6. Low power consumption

VCC6-QAB-XXX datasheet

 

Description

Vectron’s VCC6 Crystal Oscillator (XO) is quartz stabilized square wave generator with a LV
PECL output, operating off a 2.5 or 3.3 volt supply.

The VCC6 uses 3rd overtone crystals for frequencies under 200MHz, resulting in low jitter
performance, typically 0.2pS rms in the 12 kHz to 20MHz band for a 155.52MHz output, which is  three times better than competing PLL solutions.

Features

1. Output frequencies to 270 MHz

2. 0.2pS rms jitter, 12kHz-20MHz,155.52MHz

3. Enable/Disable for test and board debug

 

Applications:

1. Fiber Channel

2. Ethernet, Gigabit Ethernet

3. Storage Area Network

4. Digital Video

5. Broadband Access
