Prescaler ICs
|
| |
 |
Function: |
Provides an output signal at one nth the input frequency, where n is the division ratio (or modulus) of the prescaler. A prescaler is often used as part of a PLL to provide a low frequency signal that can be locked to a stable low frequency reference. |

Products |
| |
- HMMC series Prescalers
- The use of GaAs HBT processing results in prescalers with excellent high frequency performance. These products are offered in chip form and SO-8 package.
|
| |
1. HMMC-3002, -3004, -3008: divide by 2,4 or 8, performance to 15 GHz [chip].
HMMC-3102, -3104, -3108: divide by 2,4 or 8, performance to 15 GHz [SO-8].
|
| |
2. HMMC-3022, -3024, -3028: divide by 2,4 or 8, performance to 12 GHz.
HMMC-3122, -3124, -3128: divide by 2,4 or 8, performance to 15 GHz [SO-8].
|
 |
| |
- IFD-53 series Prescalers
- The use of high speed analog silicon processing results in specialty prescalers with good phase noise performance and operation to 6 GHz in unusually small packaging.
|
| |
1. IFD-53010: divide by 4 premium performance (6 GHz)
|
| |
2. IFD-53110: divide by 4 reduced frequency (5 GHz)
|
|
