IDT, Integrated Device Technology Inc 843003AGLFT
- Part Number:
- 843003AGLFT
- Manufacturer:
- IDT, Integrated Device Technology Inc
- Ventron No:
- 2977634-843003AGLFT
- Description:
- IC SYNTHESIZER LVPECL 24-TSSOP
- Datasheet:
- 843003AGLFT
Description
The 843003 is a 3 differential output LVPECL Synthesizer designed to generate Ethernet reference clock frequencies. Using a 31.25MHz or 26.041666MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 4 frequency select pins (DIV SEL[A1:A0], DIV SEL[B1:B0]): 625MHz, 312.5MHz, 156.25MHz, and 125MHz. The 843003 has 2 output banks, Bank A with 1 differential LVPECL output pair and Bank B with 2 differential LVPECL output pairs. The two banks have their own dedicated frequency select pins and can be independently set for the frequencies mentioned above. The 843003 uses IDT's 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements. The 843003 is packaged in a small 24-pin TSSOP package.
Features
Three 3.3V LVPECL outputs on two banks, A Bank with one LVPECL pair and B Bank with 2 LVPECL output pairs
Using a 31.25MHz or 26.041666 crystal, the two output banks can be independently set for 625MHz, 312.5MHz, 156.25MHz or 125MHz
Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input
VCO range: 560MHz - 700MHz
RMS phase jitter @156.25MHz (1.875MHz - 20MHz): 0.51ps (typical)
Full 3.3V supply mode
0°C to 70°C ambient operating temperature
Industrial temperature available upon request
Available in lead-free (RoHS 6) package
Applications
Ethernet reference clocks
Telecom and datacom equipment
Test and measurement equipment
Industrial control systems
