Part # MAX3991 datasheet

Part Manufacturer: Maxim


Part Description: MAX3991 DS

Part Details:

19-3486; Rev 1; 11/05 10Gbps Clock and Data Recovery with Limiting Amplifier MAX3991 General Description Features The MAX3991 is a 10Gbps clock and data recovery Multirate Operation from 9.95Gbps to 11.1Gbps (CDR) with limiting amplifier IC for XFP optical receivers.The MAX3991 and the MAX3992 (CDR with equalizer) 7mVP-P Input Sensitivity (BER 10-12) form a signal conditioner chipset for use in XFP trans- 0.6UI ceiver modules. The chipset is XFI compliant and offers P-P Total High-Frequency Jitter Tolerance multirate operation for data rates from 9.95Gbps to Low-Output Jitter Generation: 7mUIRMS 11.1Gbps. Low-Output Deterministic Jitter: 4.6psP-P The MAX3991 has 7mVP-P input sensitivity (BER 10-12),which allows direct connection to a transimpedance XFI-Compliant Output Interface amplifier without the use of a stand-alone limiting amplifi- LOS Indicator with Programmable Threshold er. The phase-locked loop (PLL) is optimized for jitter tol-erance and provides 0.6UI of high-frequency tolerance LOL Indicator in SONET, Ethernet, and Fibre-Channel applications. The Power Dissipation: 350mW MAX3991 output provides 27% margin to the XFP eyemask specification. An AC-based power detector toggles the loss-of-signal(LOS) output when the input signal swing is below the Ordering Information user-programmed assert threshold. An external refer-ence clock, with frequency equal to 1/64 or 1/16 of the PIN- PKG PART TEMP RANGE serial data rate is used to aid in frequency acquisition. A PACKAGE CODE loss-of-lock (LOL) indicator is provided to indicate the MAX3991UTG 0°C to +85°C 24 QFN T2444-4 lock status of the receiver PLL. MAX3991UTG+* 0°C to +85°C 24 QFN T2444-4 The MAX3991 is available in a 4mm x 4mm, 24-pin QFN *Future product--contact factory for availability. package. It consumes 350mW from a single +3.3V supply +Denotes lead-free package. and operates over the 0°C to +85°C temperature range. Applications Pin Configuration 9.95Gbps to 11.1Gbps Optical XFP Modules
